legal-info: infrastructure to collect legally-relevant material
This allows to automatically collect material that may be needed to comply with the license of packages that Buildroot prepares for the target device. The core of the implementation is made by the following parts: - in package/pkg-utils.mk some helper functions are defined for common actions such as generating a warning, producing info about a package etc; - in package/pkg-gentargets.mk, within the GENTARGETS framework, a new <PKG>-legal-info target produces all the info for a given package; - Makefile implements the top-level targets: - legal-info-prepare creates the output directory and produces legal info about Buildroot itself and the toolchain, which mostly means just warning the user that this is not implemented; - legal-info, the only target that is supposed to be used directly, depends on all of the above and finishes things by producing the README files from the various pieces.
