------------------------+---------------------------------------------------
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.
