I provide --with-* options for all optional libraries because sometimes
they do something else and sometimes they don't, and this way I provide a
consistent API to everyone building the package.  Actually, I provide
three options: --with-foo that sets the prefix, --with-foo-include that
sets the -I option only, and --with-foo-lib that sets the -L option only.
--with-foo does some work to figure out lib vs. lib32 vs. lib64, and for
some libraries it does other things instead.  (For Kerberos, for instance,
the --with-foo path is used to find the right krb5-config script to run.)
