Sync the logic that decides whether to pull in openssl with the makefile
logic that decides whether to use -lcrypto. These need to stay the same
to avoid the possibility of getting a silent dependence on a (possibly
very old) builtin openssl. Of course, all it uses -lcrypto for is MD5,
but still...

PKGREVISION -> 1.

XXX: this probably shouldn't be using MD5 anyway :-/
