If a config is does not have a prompt, it must be selected.
streamline_config.pl keeps track of all configs that select other configs.
If a config that does not have a prompt needs to be set to enable a
current module, it will add include all configs that select it.
Note, streamline_config.pl does not enable modules that are not already
enabled. It only keeps enabled those that were enabled and might be
needed to compile the current modules.

The code to find the selects of a config is after the code that
adds the depends. But if a config needed selects but had no dependencies,
it would not be set. Because the code would stop before getting to
the select.

[ Impact: fix to enable configs that need to be selected ]
