I have had gcc build all runtimes libraries separately. I think we should
device gcc build and we can disable building certain directories via
--disable-<dir>. We dont have to stash libgcc. Its not a big library and
its probably better to rebuild it along with rest of runtime libraries IMO
and probably we should have packages for each language runtime so people
who dont need C++ or Java or fortran dont have to build those. The same
should be tunable in gcc builds too.
