oeqa/selftest/sstatetests: Add test that MACHINE doesn't change target sigs 

When we change between two machines with the same tune, we shouldn't see
rebuilds of binaries. This adds a test for this using the qemux86copy
machine. We also extend the test to cover multilibs.

(From OE-Core rev: df49d7a0f80673e73f753e8650cd88a086e77245)
