Comment (by jhpalmieri):
Now I ''have'' tried a full Sage build on top of this, and the build
finishes. I guess that isn't too surprising, because mpir gets rebuilt
with Sage's GCC anyway.
I'll try again with a more carefully constructed spkg, and I'll also run
the full test suite. Here's my actual proposed patch to spkg-install:
{{{

# Finally: use MPIR's flags, plus those required by Sage for the
