Agreed. This needs testing.

You need to:

- Create a test script that is run as a test.
- The test script needs to check for gdb, this can't
  be done at host configure time because the test script
  might be run on a remote host for cross-testing via the
  test wrapper.
- If gdb is not present on the target then fail with
  UNSUPPORTED (not sure if this is possible, we usually
  mark unsupported testes by putting them into a special
  Make variable).
- If gdb is present then run it with a script (-x) and
  do some printing tests of various initialized mutexes
  and a test program, and then compare that to expected
  data (store the expected data in a file if you want)
  and return PASS or FAIL.

Carlso.
