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:
Would be nice if one of you could review this.
For testing, it should be sufficient to (try to) install the spkg with an
arbitrary Sage version (of course installed on some 32-bit Linux running
on a 64-bit processor):
{{{
#!sh
$ unset ABI # We want to test that the spkg works *without* setting it.
$ env SAGE_CHECK=yes ./sage -i
http://sage.math.washington.edu/home/leif/Sage/spkgs/mpir-2.1.3.p5.spkg
}}}
After that, you should reinstall the original MPIR spkg from your Sage
installation (with `./sage -f spkg/standard/mpir-<version>.spkg`) in case
you used a Sage version prior to Sage 4.7.2.alpha3 (into which the MPIR
2.1.3.p4 spkg from #8664, the first 2.x version in Sage, was merged).
(No need to uninstall it from Sage 4.7.2.alpha3 or if you happen to have
already installed the MPIR 2.1.3.p4 spkg, the GMP-ECM 6.3.p2 spkg and the
necessary patches from their tickets.)
You can of course in addition test the spkg on other (64-bit) platforms as
well... :-)
Thanks!
