Patch for Makefile - LIBMD_SHA1: -lmd on FreeBSD

Patch for Makefile - LIBMD_SHA1: -lmd on FreeBSD

Hello,

Once in a while I send in some patches to the FreeBSD folks for the
devel/git port. I just wrote a patch for Git that makes it possible to
link it against the FreeBSD Message Digest library (libmd), removing the
dependency on OpenSSL.

The patch adds the switch LIBMD_SHA1. When set, it just uses sha.h and
-lmd. I've also added proper documentation to the top of the Makefile.

Yours,
