[Bug c/32415] New: libgcc_s not found in library search path with --enable-version-specific-runtime-libs

["lionelb dot nospam at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Minimal program in test.c:

int main() {}

Compile:

# /var/scratch/lionelb/usr/gcc-4.1.2/bin/gcc -v test.c

Now:

# find /var/scratch/lionelb/usr/gcc-4.1.2 -name libgcc_s*
/var/scratch/lionelb/usr/gcc-4.1.2/lib/gcc/x86_64-unknown-linux-gnu/lib/libgcc_s.so
/var/scratch/lionelb/usr/gcc-4.1.2/lib/gcc/x86_64-unknown-linux-gnu/lib/libgcc_s.so.1
/var/scratch/lionelb/usr/gcc-4.1.2/lib/gcc/x86_64-unknown-linux-gnu/lib64/libgcc_s.so
/var/scratch/lionelb/usr/gcc-4.1.2/lib/gcc/x86_64-unknown-linux-gnu/lib64/libgcc_s.so.1

so it doesn't look as if gcc is looking in the right place for libgcc_s.

This problem appears to affect GCC 4.2.0 as well.
