Nicolas Pitre 7c6ef2f214 [PATCH] ARM optimized SHA1 implementation
This is my ARM assembly SHA1 implementation for GIT. It is approximately
50% faster than the generic C version. On an XScale processor running at
400MHz:

	generic C version:	9.8 MB/s
	my version:		14.5 MB/s

It's not that I expect a lot of big GIT users on ARM, but I stillknow
about one important ARM user that might benefit from it, and writing
that code was fun.

I also reworked the makefile a bit so any optimized SHA1 implementations
is used regardless of whether NO_OPENSSL is defined or not.
