This matches what the other GNU toolchain projects have done already.
The generated diff in practice isn't terribly large. This will allow
more use of subdir local.mk includes due to fixes & improvements that
came after the 1.11 release series.
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.
