	* curve25519-mul.c (curve25519_mul): Switch to use Montgomery
	ladder. About 20% faster than current Edwards curve operations.
	Difference is expected to shrink when Edwards operations are
	optimized to take advantage of the twist, but it seems unlikely to
	get significantly faster than the Montgomery ladder.

	rule for transforming .asm to .o, and drop include of asm.d.
