[Buildroot] [PATCH] Added local package support.

[Avishay Orpaz]

From: Avishay O <avishorp at gmail.com>

Local packages are packages that are local to the build and not distributed with buildroot.
They are placed in a directory named "locals" (by default) and follow the same rules
as other packages (Config.in, <pkgname>.mk, patches ..). Their configuration options
are automatically collected and placed under the "Local Packages" menu in x/menu/.../config.
