	* 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.
	Possible now since we generate a single object file from each asm
	file. This change also helps Solaris' make recognize .asm files.

	(COMPILE, COMPILE_CXX): Drop CCPIC. New variable EXTRA_CFLAGS,
	which can be set by individual Makefiles.
