configure.pl makes this same mistake/unchecked assumption on other 64
bit cpus running 32 bit operating systems (all Core2s have x64 mode
built in, so configure.pl assumes you want a 64 bit build). The only
real way to test for this case is to compile a test program under a
set of possible compilation flags and see which one(s) output working
