It's hardly worth the trouble of fixing this.  msun should become libm.
If you want to support the old library then everything should be
renamed:

	msun -> libm
	libm -> libmould (sic)

We also need dynamic support for the i387 functions.  -DHAVE_FPU is no
good because it can't be used for the distribution libraries.  Something
like

	if (_have_i387)
		result = _i387_pow(x, y);
	else
		result = __ieee754_pow(x, y);

would add less time overhead than shared linkage.
