Newlib, GCC and binutils bumps have broken things in the past and will
continue to do so. This is a development master and things have to break
periodically.

The next newlib bump picks up at least two corrections to pthread.h which
will break builds. When we update, I will.have to push my changes
correcting the prootoypes in our source.

Plus I have on my to do list to move what I think are the last three POSIX
.h files to newlib. That also is a hard break when newlib bumps.
