(In reply to comment #7)
Is the libgcc_s.so the link finds a linker script?
You can use -Wl,-M,--verbose to see what is going on.
No, it doesn't seem to.

/usr/lib/gcc/powerpc64-suse-linux/4.5/libgcc_s.so - /lib/libgcc_s.so.1
do we now install linker-scripts for libgcc_s.so? If so I have to fixup our
install procedure as I am simply doing
# Move libgcc_s around
rm -f $RPM_BUILD_ROOT/%{_lib}/libgcc_s.so
ln -sf

--- Comment #10 from jakub at gcc dot gnu dot org 2010-04-13 14:18 --- Yes, we sometimes install linker scripts, sometimes symbolic links. E.g. on powerpc64-linux, 32-bit libgcc_s.so is a linker script, while 64-bit libgcc_s.so is a symlink. If you after install overwrite it with a symlink, it won't work properly. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43727
