[libc-eglibc] Fix testing for existing files

To test for existing files, use "[ -f blabla ]", not "[ -a blabla ]"
Checking for a file exsitence with "-a" is a bashism.
Althoug we _are_ using bash, it's disturbing as it can be misread as
the 'and' operator. Fix by using "-f".

samples: add eglibc-based toolchain for MIPS.

config: add Linux kernel 2.6.30.5

config: update Linux kernel long-term stable to 2.6.27.31.

Merge the AVR32 support branch to the default branch.

Removed debug line

Fix libc config

Misc AVR32 cleanups.

Changed copyright

Update README on how to send proper patches

Add a few lines of explanations on how to correctly setup
and use Mercurial to send proper patches.

Add sections to the README

Fix typo in README

Update the README with the new URL to the project homepage

The URL for the crosstool-NG homepage has changed. Update the
README accordingly. The old URL is still valid, though.

config/gcc: re-order versions

Move the gcc-4.3.4 version to its place.

gcc: add support for 4.3.4

gcc: add patch to fix PR37436

When compiling some C++ code, GCC 4.3.x fails with an internal
compiler error. The bug report is available at
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37436. The included patch
is the one that has been merged in the trunk of gcc.

config: make CONFIG_SHELL default to bash

Some components (eg. GMP) will fail to correctly build if
the CONFIG_SHELL is not bash (eg. ash or dash). So make bash
the default CONFIG_SHELL.

Keep ash as a possible selection, as future versions of those
currently /broken/ tools may come fixed wrt to CONFIG_SHELL
being POSIX-ly compliant.

Tagging release 1.4.2

1.4: update version to 1.4.2

[complib:mpfr] Fix building MPFR in some weird cases

The tmul test uses a compiled-in input file in $(srcdir).
The problem is that the Makefile passes it unquoted. The C code
tries to stringify it using clever macros, which may *usually* work.

In my case the source directory was named:
.../toolchain-powerpc-e500v2-linux-gnuspe-1.0-2.fc10/.../tests
And guess what? During testing I found out the program fails because
it tries to open:
.../toolchain-powerpc-e500v2-1-gnuspe-1.0-2.fc10/.../tests

Yes, CPP tokenized the macro before stringifying it and not surprisingly
the 'linux' part was converted to 1.
[on Fedora-10: cpp (GCC) 4.3.2 20081105 (Red Hat 4.3.2-7)]

So the attached patch simplify the macros and pass the path as string
from the Makefile.

[configure] Fix automake version check

The configure script fails on automake-1.11 (in Fedora-11) since
it looks for 3-digit version number.

"Yann E. MORIN", added the following comment:

The check for the automake version is not against a 3-digit number,
but really against a 3-part version number, a-la 'x.y.z'. Versions
such as 1.10 and 1.11 are also valid.

Fix creating the .../lib/ directory structure in the non-sysroot case

The symbol link that is created in the sysroot directory only needs
to be made when the cross compiler is build with the sysroot option

Also set CT_DEBUGROOT_DIR for non sysroot-ed toolchains.

In the non-sysroot-ed case, the debuf-root directory would not be set;
debug tools would have been installed God-only-knows-where...

Add .hgignore file.

List all generated or temp files in .hgignore, so they
don't clutter the screen when running hg status.

populate: fix installing dynamic linker 'ld.so'

The dynamic linker, ld.so, needs the execute bit to be set.
Detect tht the library being installed is in fact ld.so and
install it with 0755 instead of 0644.

Fix detecting src == dst.

Use a simpler command to copy src -> dst.

Also change echo to printf, get rid of 'echo -n', which is
highly non-portable.

[configure] Use hg, instead of svn, to compute the version string

Now we moved from Subversion to Mercurial, use the hg command to
compute the version string.

[config] Merge CONFIG_SHELL selection.

[config] Warn againt using ash as CONFIG_SHELL

It apears that more and more ./configure scripts and Makefiles
make use of non-POSIXly correct shell constructs, that don't
work with ash.

For now, just warn the user against using ash, but keep it as
an option in case newer versions of the /broken/ components
come fixed, and we can again use ash, as it is in some cases
really faster than bash.

[config] Allow user to specify custom CONFIG_SHELL

In case the shell the user wants to use as CONFIG_SHELL is located in a
weird place (eg. /opt/bash/bin/bash), or is weirdly named (eg. bash-4),
let the user enter the patch to the shell.
