Clean up a bunch of cruft in --with-ssl; make it more resemble other

Clean up a bunch of cruft in --with-ssl; make it more resemble other
--with flags.

Report, in the messages at the end of the configure script, whether
we're building with the SSL library.

If we fail to find "sprint_realloc_objid()" when linking with a
particular library, and --with-ssl wasn't specified, try linking with
-lcrypto as well and, if that succeeds, fail with an indication that UCD
SNMP requires -lcrypto but --with-ssl wasn't specified.
