any more to say on this? i guess i'll leave startprefix with me for now.

i version bumped baselayout, although i guess it would not be strictly
neccessary - just to be safe.

there are two new packages - app-portage/prefix-chain-setup provides the
prefix-chain-setup script, which is used to bootstrap chained eprefixes.
sys-apps/prefix-chain-utils contains startprefix, and a toolchain
wrapper making it possible to use the native toolchain of another prefix
with chaining (making paths of all prefixes in play appear on the
command line - this may be slow where exec is slow, and the chain is
long - i can live with that).

i attached a complete diff (without manifests) FYI, if you like to
glance over it again - or just the parts you haven't seen.

(i'll start writing changelog right now, so those are not there... :))

Cheers, Markus
