Uses $(CPP) to attempt to preprocess an include <openssl/sha.h> directive. If that fails, NO_OPENSSL is defined, causing the Makefile to fall back to using mozilla's SHA implementation. This should possibly go to configure.ac, but maybe *also* to Makefile to make from-source compilations easier. git HEAD already comes with a Makefile (rather than a Makefile.in), so I just ran it while testing out patches. I introduced the test because I thought the computer could find out about libssl for me, rather than myself having to forget to specify NO_OPENSSL every time.
