I missed that; it's perfect, thanks!

Actually they're not, they're just the specific versions of things that 
are built to deal with the cross compile objects. In the end I added 
them to DISTFILES with the appropriate MASTER_SITES entries and 
discovered EXTRACT_ONLY and set that to the github tarball.

It'd be sweet if this worked but it doesn't. I think the problem is that
create-binary-alias happens slightly before do-configure which is the 
first place I need gcc to exist.

Thanks guys!
