Allow FEATURES to persist between phases since the user might

want to modify it via bashrc to enable things like splitdebug
and installsources for specific packages. They should be able
to modify it in pre_pkg_setup() and have it persist all the
way through the install phase. However, if FEATURES exist
inside environment.bz2 then they should be overridden by
current settings.
