This path is fraught with danger to be honest. There are some things
which are "safe" like subversion and git but they don't make that much
difference to a build and there are not as many as you'd think.

The biggest difference you can make is an sstate cache you share amongst
the pupils. The time is spent:

a) building gcc
b) building libc
c) building gettext
d) building glib

each of these is a bottle neck which then opens up a new set of targets
as none of them are ASSUME_PROVIDED material.

Cheers,
