[gentoo-alt] [PREFIX] bumped baselayout-prefix, "Stacked Prefix" with prefix-toolkit

[Michael Haubenwallner]

Another heads up:

I've rebased baselayout-prefix onto baselayout-2.6, with the prefix
patches designed for submission into baselayout, to get rid of
distinct baselayout-prefix at some point, let's see how that works.

Also, there is the new app-portage/prefix-toolkit package, providing:
* /startprefix now (overrides the one created during bootstrap),
  to get that one updateable, as well as
* prefix-stack-setup script as entry point to the "Stacked Prefix"
  world (although without any further documentation yet).

Instead of just creating /startprefix, at some time we may want to
have bootstrap-prefix.sh emerge prefix-toolkit eventually.
 
Have fun!
