[Buildroot] [PATCH 0 of 4 v2] infra: remove FOO_DIR_PREFIX, 4th param of pkg infras, pkgparentdir

[Thomas De Schampheleire]

This patch series removes a number of unused variables and helper functions.
It is a v2 of patch http://patchwork.ozlabs.org/patch/290254/
('infra: remove usage of pkgparentdir in favor of pkgdir') but simplifies
the code even more, after discussion on the Buildroot Developer Days at
FOSDEM 2014.
