Note: My CPU supports AVX instructions. The default assembler does not,
and Atlas's build process outputs a note to that respect in the beginning
of the log file ("disabling AVX" or similar). However, I replaced
/opt/local/bin/as with a script that calls a different assembler, so that
AVX instructions work fine on my system. Maybe there is a configure check
for AVX that unexpectedly succeeds?
