[Bug c++/16507] New: gcc_s not found when linking 64-bit C++

["bfriesen at simple dot dallas dot tx dot us" <gcc-bugzilla at gcc dot gnu dot org>]

Linking C++ programs fails due to either the wrong (32-bit) libgcc_s.so.1 being
installed in the compiler's default directory, or the linker search path not
being specified correctly. I am not sure what the intended operation is.

Configured with
/home/bfriesen/src/gnu/gcc-3.4.1/configure  --prefix=/usr/local/sparc64
--program-suffix=-3.4.1 --enable-shared --enable-threads
--enable-version-specific-runtime-libs --enable-languages=c,c++ --disable-nls
--with-cpu=ultrasparc sparc64-sun-solaris2.9

Note that default libgcc_s.so.1 is 32 bit, not 64-bit:
% file /usr/local/lib/gcc/sparc-sun-solaris2.9/3.4.1/libgcc_s.so.1
/usr/local/lib/gcc/sparc-sun-solaris2.9/3.4.1/libgcc_s.so.1:    ELF 32-bit MSB
dynamic lib SPARC32PLUS Version 1, V8+ Required, UltraSPARC1 Extensions

64-bit MSB dynamic lib SPARCV9 Version 1, UltraSPARC1 Extensions Required,
dynamically linked, not stripped
Note that linker search path does not look in directory containing a 64-bit
libgcc_s.so.1 (there is one in the sparcv9 subdirectory):
