The problem is that adding userspace is massively multiplicative, especially
for some arches.  Some libgccs won't build without bits of kernel headers or C
library headers - and there are multiple C libraries that would have to be
included in the SRPM as not all arches are supported by all C libraries.  At
least I'd probably have to include glibc and uClibc.

And then, which libgccs do we build?  MIPS, for example, has half a dozen, I
think, and FRV has three or four.

It may be possible to cheat and only include a few headers and not build
shared-library libgccs.

It may even be worth considering build userspace packages for certain useful
combinations if we can keep the list small.

However, my primary objective is to build as many compilers as I can for the
purpose of building the Linux kernel - even if I can't *link* the kernel due to
the lack of a libgcc.
