Makefiles: Add / Update help for makefile targets

Currently running 'make help' just gives help for the kconfig targets.

This adds help for common coreboot and toolchain targets.  It stops
    printing some of the less common kconfig targets, but still leaves
    them in the makefile as documentation.
