In addition to the comments so far about what the testsuite framework
should be doing, I also think the sparc option processing is currently
doing the right thing given the input seen here.

If you say "-mcpu=cypress -mvis" which is what the command line amounts
to, it meant to enable VIS and that requires turning on V9 also which is
what the option processing in the sparc backend does.
