There is a major difference between -mcpu and -march. -mcpu is for tuning
(optimization). -march is a minimum requirement.

Hence this change makes VLC-win32 unusable on 486 and first-gen Pentiums.
Considering that we barely support Win98, and that these boxes typically
run Win95, I do not disagree with the change - but I hope it is well
understood. If this is not intended, you may prefer to use -mtune. That is
the new name for -mcpu with not-so-old GCC.

Note that -march=i686 implies -mcpu=i686, so the older option is pretty
useless now.
