Subject: [PATCH] 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.

(cherry picked from commit 48545a8f724247853c5b1d4e0a24e3ea3ee06515)
