description:
don't fail the build just because we don't know how to check for cpu
features on ARM. it doesn't seem to be a problem if /cpu/procinfo is
empty as in netbsd/arm nor if procfs is unmounted.

+Don't error on ARM if we're not on linux or MSVC.
+Currently the code attempts to open /proc/cpuinfo, and tests for
+failure - if that doesn't contain useful info or doesn't exist,
+it still behaves correctly.
