Comment:
You can finally find a rebased spkg where I discarded some stuff involving
ABI which previously made sage print that it was building for 32 bits,
whereas it actually had no effect, and which is rebased on #12131 at the
usual address:
http://perso.telecom-paristech.fr/~flori/sage/mpfr-3.1.0.spkg
I guess the issue with doctests is the last step before "needs review"
