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.

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

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.

[config] Add bash as a possible CONFIG_SHELL

On some systems and/or for some components, it may be necessary to
explicitly use bash as the shell used by ./configure and Makefiles.

[config] Change the way to select the CONFIG_SHELL

Transform the single boolean option to a 'choice' selection
with two options: "sh" and "ash".

This is needed to later add "bash" as override.

Merge the queue with all new component versions.

Make it build again for non-local use.

Check paths sanity before they get used.

Don't use the PATHs before they get checked for sanity.

Better check for spaces in paths

Spaces are evil in paths. Print the path that contains a sapce.
Don't print computed paths, as they'rebased on provided paths,
and don't get space added into them.

[functions] Allow newlines (\n) in log messages

Allow caller to log messages with embedded newlines when calling
CT_DoLog and other logging functions (eg. CT_Abort...).

[finish-step] Fix the tools wrappers

[configure] Use hg to compute the version string

Now that we have migrated to hg from svn, it does not make sense
to keep using svn tools to compute the version string, so switch
to using mercurial tools (that are much more flexible, BTW).

populate works internally.
