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).

Vampirise patches for binutils 2.17 from buildroot.

Remove the superfluous _config suffix to preconfigured targets (in "make help").

Update tools/config.sub to latest from gnu.org

Add uClibc-0.9.29_rc1.

Add linux 2.6.21 and 2.6.21.1 for headers_install.

Some little cosmetics in final compiler.
