I don't think it's practical to add a separate-build requirement to
libobjc; if nothing else, the tm.h inclusion makes it even more
closely tied to gcc/ than libstdc++ sources are now.  It's also not
very useful to compile with any compiler other than GCC.  So let's
just commit to making GCC's libobjc the only one that GNUStep would
ever need.
