util/abuild: Clean up the missing_arches check

This change adds the following improvements:
* Easier to read.
* Checks to see if .xcompile is complete.
* Checks the make return code. This will catch if .xcompile is missing.

BUG=b:112267918
TEST=Modified my .xcompile and ran abuild and verified that
missing_arches got set correctly. Also deleted .xcompile and verified
there was a failure.
