nasm: Upgrade 2.13.03 -> 2.14
The patches are all backports or have equivalent changes in the new release so can be dropped. Upstream reworked the install handling to use DESTDIR instead of INSTALLROOT and we no longer need to create directories.

Subject: [PATCH] eval: Eliminate division by zero
|

|

When doing division we should detect if the value we're
|

divided by is not zero. Instead of is_unknown() helper
|

we should use is_just_unknown().
