[Buildroot] [PATCH 0 of 5 v3] 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 v3 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 and further input of Arnout.

[Buildroot] [PATCH 1 of 5 v3] infra: remove redundant $(call) on pkgdir, pkgname, pkgparentdir

[Thomas De Schampheleire]

When calling make 'functions', the $(call) keyword is only needed if the
function takes arguments. For pkgdir, pkgname and pkgparentdir this is not
the case, so we can remove the call to make things more readable.

[Buildroot] [PATCH 2 of 5 v3] infra: remove variable FOO_DIR_PREFIX

[Thomas De Schampheleire]

Variable FOO_DIR_PREFIX in inner-generic-package isn't really needed. The
contents of this variable are 'package' for normal packages, 'boot' for
bootloaders, and 'linux' for the linux kernel.
When patching a package, all you need to know is the directory where
patches can reside, which is already returned by $(pkgdir). In order to be
able to use this variable outside of inner-generic-package, we introduce a
target-specific variable PKGDIR that equals to this $(pkgdir).

[Buildroot] [PATCH 3 of 5 v3] infra: remove usage of 4th parameter to inner-generic-package

[Thomas De Schampheleire]

In preparation of the removal of the 4th parameter to inner-generic-package
and the pkgparentdir helper function, this patch removes the direct usage of
this 4th parameter. The remaining usage
ifeq ($(4),boot/)
can become
$(filter boot/%,$(pkgdir))
instead (and similar for toolchain).

[Buildroot] [PATCH 4 of 5 v3] infra: remove unused 4th parameter to package infrastructures (pkgparentdir)

[Thomas De Schampheleire]

The fourth parameter to inner-generic-package is no longer used. Removing
this parameters requires renaming all usages of $(5) to $(4), and updating
the calls to inner-generic-package (and equivalent for the other package
infrastructures).
