Mike Frysinger ed20821a40 newlib: migrate from INCLUDES to AM_CPPFLAGS 
Since automake deprecated the INCLUDES name in favor of AM_CPPFLAGS,
change all existing users over.  The generated code is the same since
the two variables have been used in the same exact places by design.

There are other cleanups to be done, but lets focus on just renaming
here so we can upgrade to a newer automake version w/out triggering
new warnings.

README 

This directory was an experiment to use floating-point operations to implement
the math library when a processor had a floating-point instruction set.  The
experiment was a failure in that some of the algorithms chosen (e.g. recursive
algorithms for sin/cos, etc..) are too simple and do not provide proper accuracy 
nor handle very large or very small inputs adequately.

The code is considered moth-balled.  The stable math library routines can be
found in libm/math and the configuration option to use this has been removed.

If you wish to experiment with the concept, please feel free and report back if
you have major improvements.
