Use a model of fake FILESDIR path to ensure that invalid accesses to
FILESDIR will result in failures rather than being silently allowed by
Portage. This mostly involves accesses in the global scope and pkg_*
phases, although the current model does not cover the latter completely
(i.e. does not guarantee that the directory is removed post src_*).
This model aims to follow PMS wording quite precisely. The value of
FILESDIR is meant to be stable throughout the build process, and it is
reliably set to a temporary directory path. However, since the path is
not guaranteed to be present outside src_*, the directory symlink is not
actually created before src_* phases.
== Review notes ==
This is the final version that actually works ;-). I did a full egencache
run with it and the only packages that fail are eblit users (all of them
have bugs open with deadline 1 week from now). There might be a few more
silly failures, so I'll test it for a while, and ask Toralf to possibly
do some tinderboxing.
