In order to simplify determining the right extractor tool for a given
file type, this patch introduces a make function 'suitable-extractor'.
Its usage is $(call suitable-extractor,filename), and it returns the
path to the suitable extractor.

Some packages (kmod, e2fsprogs, ..) contain multiple (different) license
files with the same file name, but in different directories.
These are currently all copied to the same filename in
output/legal-info/licenses/<pkg>, overwriting everything but the last file.
Fix it by recreating the same directory structure under legal-info.

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.

This patch adds a few utility functions to pkg-utils.mk.
Functions finddirclauses and findfileclauses help in building a find command
that skips a set of directories and performs operations on a set of files.
This pattern can for example be used to keep certain files or directories from
being stripped, or to remove certain files from a package installation.
The notfirstword function is the inverse of the 'firstword' function in make:
it returns all but the first word.
