[Buildroot] [PATCH 1 of 4 v2] infra: remove variable FOO_DIR_PREFIX

[Yann E. MORIN <yann.morin.1998@free.fr>]

Maxime, All,

On 2014-02-04 17:21 +0100, Thomas De Schampheleire spake thusly:
> 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).

Maxime, I guess that's the variable we needed, and were desparately
looking for in the tree, when hacking spidermonkey during our wayback
trip from Brussels! :-)

Regards,
Yann E. MORIN.
