Subject: configure: check yasm/nasm for working pextrd opcode
X-Git-Tag: android-x86-4.4-r1~12310^2~2312
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=48545a8f724247853c5b1d4e0a24e3ea3ee06515;p=android-x86%2Fexternal-ffmpeg.git

configure: check yasm/nasm for working pextrd opcode

NASM versions older than 2.08 fail to build ffmpeg with several
"error: operation size not specified" errors but this is not caught in
configure.

Fix that by checking if "pextrd [eax], xmm0, 1" works in configure.
