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

I don't think so, the linker would have complained about ELF class mismatch.

Neither, I see -L/usr/local/sparc64/lib/gcc/sparc64-sun-solaris2.9/3.4.1 and
libgcc_s.so should be there because of --enable-version-specific-runtime-libs.

Note that you don't look at the right place.  According to your prefix
/usr/local/sparc64 and your target sparc64-sun-solaris2.9, the path should read:
% file /usr/local/sparc64/lib/gcc/sparc64-sun-solaris2.9/3.4.1/libgcc_s.so.1

This suggests that the compiler was not properly installed, or maybe not
installed at all.  Please try again to issue "gmake install".

[As a side note, specifying -mcpu=ultrasparc doesn't imply 32-bit mode.]
