there are issues about using 'gcc -o /dev/null':
/usr/bin/ld: final link failed: File truncated
collect2: ld returned 1 exit status
So we test that and use /dev/null in environments where it
works, while using an .INTERMEDIATE file on those where it can't
be used, so that the .perf.dev.null file can be used instead and
then deleted when make exits.
