Is there still a good reason for libm.a to be separate from libc?  It
seems to me that
	#include <math.h>
	main() {
		double d = sqrt(2.0);
		return 0;
	}
should link and run with libc, as libc is "the standard library" and
sqrt is (AFAIR) ANSI standard.

I don't see how much we gain from the separation.  If it does much good,
though, maybe we should go the other way, and separate things out a bit
more.
