tiny improvement to config(8)

[Chris Pressey <cpressey@xxxxxxxxxxxxxxx>]

'lo all,

The attached patch makes an ever-so-tiny improvement to config(8):
it adds a -q ("quiet") flag which suppresses reminder messages.

The idea is that the message "Don't forget to do a ``make depend''" is
(at best) redundant and (at worst) confusing, when using the "new"
kernel building method (which is virtually standard nowadays.)

To try it, you can run

  make buildkernel KERNCONF=FOO CONFIGARGS="-q"

This is working fine for me, and the patch is so simple, I am fairly
confident there are no errors in it.

I'm planning to do much more intensive work on config(8) soon, I'll post
to the kernel list later today detailing my plans.
