Exit code 2 is already in use in arm/run. Now that I'm looking more closely at it, exit code 2 is already in use in run_tests.sh, same for mkstandalone.sh and arm/efi/run. How about using 3 everywhere as the exit code? Also, your idea (below) to use a function to test for supported $TARGETs is a very good one, I'll do it in the next iteration.
