Upgrade scripts/tarball.sh and scripts/saveSample.sh to use the new logging facility.

Move the config script for the build dir to the source dir.
That will be useful when we have the restart functionality.

Fix gdb to install in CT_PREFIX_DIR rather than CT_INSTALL_DIR.
One day, I swear, I will implement the install directory option. But later.

Ah! I finally have a progress bar that doesn't stall the build!
- pipe size in Linux is only 8*512=4096 bytes
- pipe size is not setable
- when the feeding process spits out data faster than the eating
process can read it, then the feeding process stalls after 4KiB
of data sent to the pipe
- for us, the progress bar would spawn a sub-shell every line,
and the sub-shell would in turn spawn a 'date' command.
Which was sloooww as hell, and would cause some kind of a
starvation: the pipe was full most of the time, and the
feeding process was stalled all this time.

Now, we use internal variables and a little hack based onan offset
to determine the elapsed time. Much faster this way, but still
CPU-intensive.

Forgot to svn add...

Add gcc-4.2.0 (EXPERIMENTAL) and some patches vampirised from buildroot (302 rediffed against 4.2.0).

Fix adding versions for the core C compiler.

Add uClibc-0.9.29:
- associated patch set
- update the munging function to accomodate the new config variables
libfloat version was missing from the previous commit... :-(
Better handle the case where the sample directory already exist but isn't under revision control, and in case the destination file doesn't exist in the sample directory.

Correctly handle the libfloat case: download, extract and patch sub-actions.
Small improvement in messages in scipts/functions when retrieving a file.

Remove an incorrect path from uClibc-0.9.29: we _do_ need a xgcc to buld this header!

Un-mark gdb and dmalloc being EXPERIMENTAL.
Mark native gdb as being EXPERIMENTAL (it depends on termcap, which we don't have yet).

Little fix up in a message during the dmalloc build.

Add dmalloc debug library facility.
Add patches for dmalloc.
Ignore the generated config/debug.in

Really use local copy first in case it does not have the same extension as the downloadable tarball.

Remove even more documentation.

Reverting to uClibc-0.9.28.3, as 0.9.29 spawns incorrect bits/sysnum.h (needs a xgcc first!).

Bah, forgot to ci CREDITS...

Patches for glibc-2.5, courtesy of "Robert P. J. Day" <rpjday@mindspring.com>

Make the debug config menu a generated file.
Add a uClibc-0.9.29 patch directory with one patch (from me!).
Update the armeb-unknown-linux-uclibc sample to uClibc-0.9.29.
Some eyecandy in the gdb build process.

Debug facilities:
- add a framework to easily add new ones
- add gdb as a first debug facility
- add patches for gdb
After the kernel checked its installed headers, clean up the mess of .checked.* files.
Reorder scripts/crosstool.sh:
- dump the configuration early
- renice early
- get info about build system early, when setting up the environment
- when in cross or native, the host tools are those of the build system, and only in this case
- elapsed time calculations moved to scripts/functions
Remove handling of the color: it's gone once and for all.
Update tools/addToolVersion.sh:
- handle debug facilities
- commonalise some code
- remove dead tools (cygwin, tcc)
Point to my address for bug reports.

Move the whole threading ;odel choice out of glibc and into the generic C library options: even uClibc may have NPTL at one point in the (hopefully near) future.
Mark the progress bar as being CPU-intensive.
Little style fix to the core C compiler build step.

Quiet some messages from the configurators. We don't need them.

Oupsss... Didn't save scripts/crosstool.sh prior to comiting. :-(

update the documentation somewhat. Still not complete, though... :-(

Remove dead entries for components not yet integrated: cygwin kernel, tcc...
Some fixups in config entries, to avoid warnings when parsed by the kconfig parser.

Update version to -svn.

Mark version 0.0.2.

Correctly handle the version string, defined in a single place now.
Fix and update README.

New make target to save the configured nad built!) toolchain.

Like tweak to the armeb-xscale-linux-uclibc sample to not renice the build.

Update the way we handle directories supplied by the user:
- the tarball directory is considered as a local copy, and tarballs are copied to a working area,
- the sources and build directories (CT_SRC_DIR and CT_BUILD_DIR) are now computed, and no longer an option,
- the build dir has been renamed from 'build' to 'targets'.
That should ease preparing a tarball of the resulting target.

Clean the sample saving script.

libfloat is a component by itself, not a sup-part of the C library.

Again, some progress bar optimisation.

Hop, a somewhat more efficient progress bar, less CPU consuming, if that was a problem :-)
(a litlle recreation while toochains are building...)

Beautify the progress bar.

Fix handling of downloader output: they are now correctly logged using the internal log facility.

Huge fixes to glibc build, so that we can build at least (and at last):
- use ports addon even when installing headers,
- use optimisation (-O) when installing headers, to avoid unnecessary warnings (thanks Robert P. J. DAY for pointing this out!),
- lowest kernel version to use is only X.Y.Z, not X.Y.Z.T,
- a bit of preparations for NPTL (RSN I hope),
- fix fixing the linker scripts (changing the backup file is kind of useless and stupid);

Shut uClibc finish step: there really is nothing to do;

Add a patch for glibc-2.3.6 weak aliases handling on some archs (ARM and ALPHA at least);

Did not catch the make errors: fixed the pattern matching in scripts/functions;

Introduce a new log level, ALL:
- send components' build messages there,
- DEBUG log level is destined only for crosstool-NG debug messages,
- migrate sub-actions to use appropriate log levels;

Update the armeb-unknown-linux-gnu sample:
- it builds!
- uses gcc-4.0.4 and glibc-2.3.6,
- updated to latest config options set.

Inform that a component is already extracted.

Print the elapsed time alongside with the progress bar, such as below:
[02:27] \

Cosmetics: newline at end of file, ports are now a separate option.

Print the major components and their version when calling "make help".

Bah. Be silent when there is nothing to do: glibc has no config (file) to check.

Remove the incomplete i686-unknown-linux-uclibc sample.

Update the i586-geode-linux-uclibc sample.

Don't make checking the kernel config file a step by itself. Only make it a step if we need a not-provided kernel config file.

Bah, the arm-qemu-linux-uclibc sample isn't usefull. Base your work on the armeb-unkown-linux-uclibc sample instead.

Update the mips-unknown-linux-uclibc sample:
- LFS is needed to properly compile libstdc++ (pity),
- globally update to the latest set of options.

Update armeb-unknown-linux-uclibc sample:
- no need for the kernel .config file,
- globqlly update to latest set of options.

Simplify kernel config file need.
Don't build a default config file when not needed.

Don't print directories as we descend into them.

Fix glibc and uClibc downloading and extracting.
Although we no longer need the kernel config file, we now need to specify the kernel source directory when installing headers.
Re-order components downloading to match build order.
Fix the saveSample.sh script in case the referenced files are the same as the destination files.

Merge the save-sample branch to trunk:
- reorder most of the environment setup,
- geting, extracting and patching are now components' sub-actions,
- save the current config as a sample to be used as a pre-configured target.

Linux kernel headers install does not need the kernel to be configured. Dropping this unneccessary step.

Introduce an OBSOLETE config option, to mask-out legacy stuff.

Add uClibc-0.9.29 now it's out, and remove the 0.9.29-rc1.

Rename the MIPS toolchain: it's not qemu-specific!

Final merge from the MIPS branch.

Update CREDITS.

Merge patches sent by Robert P. J. Day <rpjday@mindspring.com>.
Warning: the buildroot folks purposedly removed the skip-comment patch but didn't really said why. Keeping it for the sake of having it in svn just in case (removing it will be easier thant not having it at all).
