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".)
