Merge remote-tracking branch 'qatar/master'
* qatar/master:
build: improve rules for test programs
build: factor out the .c and .S compile commands as a macro
swscale: remove unused xInc/srcW arguments from hScale().
H.264: disable 2tap qpel with CODEC_FLAG2_FAST and >8-bit
H.264: make filter_mb_fast support 4:4:4
mpeg4videoenc: Remove disabled variant of mpeg4_encode_block().
configure: allow post-fixed cpu strings for athlon64, k8, and opteron when setting the -march flag.
Move some variable declarations below the proper #ifdefs.
Conflicts:
