I believe what you are looking for is 'make defconfig'.  This will 
provide a basic set of configuration options to get you going, then
you'll have to edit the things like processor family, processor type,
whether you want uClibc vs {e,}glibc, etc.

The default config is usually okay for a first attempt, however, I like
to provide to others in my company a set of config files to choose from.
Those, I derive from just cranking through the menuconfig and save the
options off when I get done.

If you are looking for more than this, there are a few other default
config files to attempt.  To list those config files do a 'make help'.

Hope this helps!
