theres a big chunk of configure.in that can be wiped out..its gcc's job to keep track of all that fun arch stuff. --enable-optimize should pass right thru to -march, which will automagically enable the appropriate stuff like -mtune=, -msse2..so you can do an #if defined (__sse2__) or wahtever... instead of the -DDONNTUSESIMD and redundant arch flag stuff...

did i mention i love autoconf??

i could try cleaning it up, but not before getting past this:
