Fabio Porcedda - Oct. 18, 2013, 9:27 a.m.
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, example:

	make clean <package-name>

Also remove TARGETS_ALL because the only purpose was to add toolchain
dependency so it's superseded by this commit.

To prevent circular dependency add the new variable <pkgname>_TOOLCHAIN
for not adding the toolchain dependency for toolchain packages.

This is also a step forward supporting top-level parallel make.
