Fix gcc version checks for _mesa_bitcount
- Fix _GNUC__ typo in both checks - Fix logic error in check for gcc < 3.4 that breaks for gcc 2.x & older Without this fix, builds with gcc 3.4.x end up depending on undefined _mesa_bitcount instead of gcc's __builtin_popcount. NOTE: This is a candidate for the stable branches. Signed-off-by: Alan Coopersmith <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
