Subject: configure: correct NASM-configuration on 32bit BSD

This patch was adapted from FreeBSD:
https://svnweb.freebsd.org/ports/head/multimedia/libass/files/patch-configure.ac?view=markup
and was also applied in DragonFlyBSD (eventhough DragonFlyBSD dropped
32bit support in 2014)

closes https://github.com/libass/libass/issues/451
