confcache

It can (or used to be able to) be used with portage, though I think it
is discouraged because it can cause some other problems. I used it for
a while and never noticed any ill effects, but maybe I wasn't looking
in the right places. I read enough about it being bad that I stopped
using it out of fear.

The better time-saver is probably parallel emerges (emerge -j) which
can configure multiple packages at once. It also has quirks but works
most of the time. :)
