[Buildroot] [RFC 1/4] package: add toolchain dependency to inner-generic-package

[Fabio Porcedda <fabio.porcedda@gmail.com>]

This commit makes the dependency from the target toolchain explicit.
This way we can buid from command line a package that use
innger-generic-package right after the configuration phase.

This is a step forward top-level parallel make.
