As discussed on sage-devel, mpir does not build on Skylake chips. As reported by Bill Hart,

We know what the problem is now, but don't have a working patch to fix it.
It's the JMPENT macro in mpn/x86_64/x86_64-defs.m4 that doesn't work
on 64 bit OSX. Details of the issue can be found
here.

In the end, the fix was to edit jump labels in a (large) number of MPIR's asm files, and change the .section type of jumptables, while leaving JMPENT macros intact. The changes are way too big for Sage patches (and done against the master rather than against meanwhile a bit outdated 3.0.0 version), thus a new tarball.
