fix libwwwapp dependencies

When letting automake compute _DEPENDENCIES for us, it's dropping all
configure-related variables (like WWWXML). There are only 2 exceptions
and are not what we're looking for here.
The fix is to supply ourselves the _DEPENDENCIES with the configure
variables are they're not going to be killed.
