[MPlayer-cvslog] r22715 - trunk/configure

Log:
Fix configure -march detection for athlon-xp

The configure script uses SSE support to distinguish between athlon and
athlon-xp, but SSE support was tested _after_ deciding the basic CPU
type. Thus athlon-xp was always misdetected as athlon. Fix this by
moving the CPU extensions check before the CPU type check. Patch from
Andrew Savchenko, bircoph list ru.
