ASM_NASM test fails on FreeBSD

[kevmeister]

I am attempting to build 2.70 on FreeBSD and failing with an error in testing for the version of nasm.

nasm --version on BSD returns "NASM version 2.13.02 compiled on Dec 31 2017". This is not currently recognized by the script, at least according to what I find in CMakeError.log. I have looked around trying tofind the script generating this error, but have ahd no luck. I have no experience with cmake, which is probably the issue.

Can anyone give this newbie a clue?

Better to use yasm with recent versions
