 Building a few of the PowerPC BSPs with `RTEMS_DEBUG = True` generates
 these warnings:

 The `score` headers `basedefs.h` header depends on `assert.h` and
 `assert.h` includes `basedefs.h` at it's top.

 I think this ticket should be set to `blocker` for the 6.1 release. We
 should resolve this and the warnings before we make a release.
