This question would be more appropriate for the mailing list
gcc-help@gcc.gnu.org.  Please take any followups there.  Thanks.

What version of gcc are you using?

Exactly how did you run the configure script?

The -B option tells gcc where to find passes, but it does not normally
tell the dynamic linker where to find shared libraries.  Something is
causing the dynamic linker to think that it should use
/a/linux/.powerpc/gcc/obj/./gcc/libgcc_s.so.1 rather than
/lib/libgcc_s.so.1.  Is it possible that you have LD_LIBRARY_PATH set
in the environment?
