newlib: libm: integrate tests subdir

Integrate the old libm/test/ subdir into the main build.  It hasn't
been used in a long time causing the code to rot a bit.  I've fixed
some of those, but it still fails for many ports, so it's disabled
by default.  People who want to take a closer look can run:
$ make libm/test/test
