Since a longer time bootstrap is broken for powerpc-unknown-linux-gnu, 32-bit
at least. The interesting condition is, it only fails when the bootstrapping
compiler is > 4.2.x, iow. 4.3.x and 4.4.x (Well 4.4 I did not confirm myself)

The failure started with r132589, this commit itself does not contain a fault
per se. It is just uncovering the issue.

The failure manifests itself as:
gcc  -g -fkeep-inline-functions -DIN_GCC   -W -Wall -Wwrite-strings
-Wstrict-prototypes -Wmissing-prototypes -Wcast-qual -Wold-style-definition
-Wc++-compat -Wmissing-format-attribute -pedantic -Wno-long-long
-Wno-variadic-macros -Wno-overlength-strings -fno-common  -DHAVE_CONFIG_H  -o

The bootstrapping compiler has this version:

[andreast@mini objdir]$ gcc -v
Using built-in specs.
Target: ppc64-redhat-linux
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man
--infodir=/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla
--enable-bootstrap --enable-shared --enable-threads=posix
--enable-checking=release --with-system-zlib --enable-__cxa_atexit

--enable-secureplt --with-long-double-128 --build=ppc64-redhat-linux
--target=ppc64-redhat-linux --with-cpu=default32
Thread model: posix
gcc version 4.3.0 20080428 (Red Hat 4.3.0-8) (GCC)


The configuration flags used:

/home/andreast/devel/gcc/head-clean/gcc/configure
--prefix=/home/andreas/devel/gcc/head-clean/testbin --disable-static
--enable-languages=c

With Janis and Peter B. we found a workaround to bootstrap again:

Basically we need a very recent binutils (I use (GNU Binutils)
2.19.50.20080922) and a tweak to link cc1: --relax.

I'll attach the workaround patch later.

Due to the fact that I do not know on how to go on I have to file this PR.
I'll add Janis and Peter to CC as they did a big contribution in analyzing this
issue.
