Only if you specify "--enable-proc-opt". (With a properly configured
build system. If you've got a broken toolchain or your system itself is
broken or you're doing a cross-compile and haven't set everything up
properly, it's possible for MMX not to be automatically enabled even
with "--enable-proc-opt".)
