Log Message:
x264-devel: if we don't pass the assembly test, e.g. if we don't
pass optimizing flags (like default netbsd setup), just act as if
we passed --disable-asm, as opposed to passing it for netbsd/arm.

- now other operating systems that don't optimize won't fail here.
- if someone does pass optimization, he benefits from it
- I don't have to define another case in the Makefile for MIPS
