AFAIK, libgomp is a runtime library and can be built entirely
separately from gcc - it doesn't need to be tangled in with it. I'd
rather see a libgomp.mk that uses the gcc tarball (possibly gcc-core
if untarring time is important) and depends on pthreads.

I haven't tested this exactly, but have built pthreads and libgomp
together in a separate makefile - that was mostly motivated by code
organisation and turnaround time in testing. I'm happy to do some
experimenting - is there a small test program to verify openmp support
is working?
