OK, I've pushed a patch that should choose this command line when the 
'-static' flag is passed to 'urweb'.  Does it work?

I'm a little nervous about my change, which hardcodes "-ldl -lz".  I 
hope all platforms' OpenSSL libraries have the same dependencies!  The 
Autoconf macro for OpenSSL that I pulled from somewhere doesn't seem to 
be setting environment variables that I could use to do this "right."
