Fix configure options using AC_ARG_ENABLE

Configure options to disable some features, which are checked using
AC_ARG_ENABLE can be invoked with --enable-<option> as well.
The current configure script always generates a #define for such options
even though the --enable-<option> case should not generate a #define.
Fix this by properly checking if the feature should be enabled, in which
case no #define is being generated.
