configure: Correctly handle all cases when using AC_ARG_WITH().

In a lot of cases only "$withval" != "yes" and "no" had been handled when the
option had been given. Therefore, the option had been ignored if no argument
had been passed to the option, making --with-<option> and / or
--without-<option> a no-op. This patch fixes this issue.
