newlib does provide a libm.  I see that the glibc flt-32 functions
have this comment:

 * Conversion to float by Ian Lance Taylor, Cygnus Support, ian@cygnus.com.

I did that conversion when I introduced this code, originally written
at Sun, into newlib.  So I suspect that the glibc float support was
taken from newlib.
