What that does is to select "-lcrypto" (and "-lz", but that's not
relevant now) out of the LIBS variable.  The configure script
should have included that in LIBS if you specified
--with-openssl, but maybe it failed to.  Can you check the
configured value of LIBS (in src/Makefile.global) to see?

If it's not there, it would be useful to see the contents of
the config.log log file.
