Hi,
Below test is supposed to be compiled and run, but we failed to link
the binary with tiny memory model.

In my understanding, dg-do run test case should be marked as
FAIL&UNRESOLVED if binary file can't be generated. But here it's
categorized as an UNSUPPORTED test. This could be mis-leading
sometimes since unsupported test could be ignored.
Any idea why it acts in this way?
Thanks,
