I just looked into this. It appears the bug only tickles when CFLAGS are
set. ie: if CFLAGS are set in the environment, it guesses the wrong ABI
when building 32-bit x86 on 64-bit AMD hardware (not sure about Intel).
You can easily reproduce this by setting CFLAGS then running ./configure.
Issue is exacerbated due to GMP's "tricked up" config.guess ie:
The CFLAGS aspect at least explains why everyone is not seeing this.

No. See above.
