h8300 and mn10200 wrong code

[Alan Modra]

I'm not sure what our policy is with regards to xfails in the
testsuite, but I'm inclined to think we should only xfail tests where
the target doesn't support the feature being tested, or where some
target peculiarity makes the test fail but the target does in fact
correctly support the feature under test.

For the testcase below, which is testing a simple difference of two
forward referenced labels, both h8300 and mn10200 will silently
generate wrong code.  I don't care enough about either target to fix
them, but I also think we shouldn't hide this type of failure.

	* gas/all/gas.exp (do_930509a): Don't xfail h8300 and mn10200.
