insane.bbclass : Disable tests for unsafe references in binaries and scripts.
These test look for programs in / that depend on programs in /usr. After
a brief discussion in #oe, we decided these tests should be disabled so
we can focus on more serious QA issues.
If you are working on a system where / and /usr are on different partitions,
you should turn these tests back on and resolving the QA warnings.
