Tried applying all the patches in gcc30s2.zip and redoing everything.  All
of the patches except for libstdc++-v3/src/Makefile.am.diff applied
cleanly (I left Makefile.am as-is).

End result was exactly the same (still had to explicitly include crt0.o,
libc, libgcc, and libstdc++ when linking, still got multiple definitions
of __register_frame_info, still got undefined references to setlocale,
toupper, and tolower). :(

The ever-hopeful,
