Summary: GCC 4.3.1 fails with cannot compute suffix of object
files
Description:
from buildroot-20080731.tar.bz, only things selected are gcc 4.3.1 and
EABI.

For those eager to get gcc-4.3.1 running. I've found out that gcc does not
find the shared objects of two libs. The attached patch points gcc to the
right directories. It is just a quick fix but it should do until there is
an official bugfix. This is what to do:
make <= will stop with the above error
cd buildroot/toolchain_build_ARCH
patch -p2 < gcc-4.3.1-compile.patch
rm -Rf gcc-4.3.1-initial
make <= should compile

Issuing 'export
LD_LIBRARY_PATH=$PWD/toolchain_build_arm/mpfr/lib:$LD_LIBRARY_PATH' from
the top of your buildroot tree makes build happy.

Using buildroot from SVN 23530. Working towards architecture i586 with
uClibC snapshot as of today. The patch didn't work (no change in
behaviour) after modifying the file by hand.
The export LD_LIBRARY_PATH also needed to include "gmp" in the path. This
makes it go further, but still doesn't work all the way.
export
LD_LIBRARY_PATH=$PWD/toolchain_build_i586/mpfr/lib:$PWD/toolchain_build_i586/gmp/lib:$LD_LIBRARY_PATH.
You need to at least run make from "gcc-4.3.1-initial", as running from
the root it detects LD_LIBRARY_PATH is based on the current path and says
that won't work.
The compilation dies when compiling mudflap at the same stage:
checking for i586-linux-uclibc-gcc... (xgcc here)
checking for C compiler default output filename... configure: error: C
compiler cannot create executables
Looking at the mudflap config.log, we see:
$ less i586-linux-uclibc/libmudflap/config.log
