Comment (by mojca):

 I would say that at the moment it would already help to test whether the
 compiler itself builds at all and provide feedback to the upstream ticket.

 Current sources don't build at all.

 Running a test suite would of course be nice to reveal other potential
 problems, but getting the build to succeed in the first place seems most
 important right now. If the build succeeds, you could more easily test a
 couple of random ports with it.
