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. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> (cherry picked from commit 48545a8f72)
