The libmvec benchmarks print a message indicating that a certain CPU feature is unsupported and exit prematurelyi, which breaks the JSON in bench.out. Handle this more elegantly in the bench makefile target by adding support for an UNSUPPORTED exit status (77) so that bench.out continues to have output for valid tests.
