I believe you can omit the testcase for certain targets by mangling
the 'target' field of dg-do. Grepping through the gfortran.dg
testsuite yields a few examples which look like:

> { dg-do run { target { ! { pdp11-*-* } } } }

Presumably you could omit errors/warnings on a case-by-case basis similarly:

> ... { dg-error "Array too big" "" { target { ! { pdp11-*-* } } } }
