Documentation-only change:

- add a reference to the config(5) manpage;
- hopefully clarify the format of the 'env FILENAME' directive.

I am putting these notes in sys/${arch}/conf/GENERIC and not
in sys/conf/NOTES because:

1. i386/GENERIC already had reference to a similar option (hints..)
   and to documentation (handbook)

2. GENERIC is what most users look at when they have to modify or
   create a new kernel config, so having the suggestion there is
   more effective.

I am only touching i386 and amd64 because the other GENERIC files
are already out of sync, and I am not sure what is the overall plan.
