New description:
MPIR fails to build on '''32-bit''' operating systems running on
'''64-bit''' processors if `CFLAGS` contain `-m32` and `ABI` is '''not'''
set.
The simple solution is to set `ABI=32` in this case, which the new spkg
now does (on Linux, where the issue occurred). It also sets `ABI=64` if
the operating system supports it, and `ABI` isn't already set, and prints
according messages.

Comment:
Replying to [comment:3 leif]:
> Oh, one more thing: I cannot test whether the GMP-ECM and MPFR spkgs
have the same problem (since they use GMP's / MPIR's `CFLAGS`), i.e., also
fail on such systems if `ABI` isn't set. If you find the time, you could
also check this by unsetting `ABI` and reinstalling them (with `./sage -f
...`).
The new mpir spkg installs here on my 32-bit OS with 64-bit processor with
ABI unset.

It also installed on an amd64 to which I have access. The ECM and MPFR
spkgs reinstalled correctly with ABI unset on both the 32-bit and amd64
machines. A positive review here.
