Cover letter [Buildroot] [PATCH 0/1] Makefile: add variable print capabilities

I just got started with buildroot yesterday, and like it :-).
I am no Makefile expert, then often I turn into wanting to check Makefile variables. This patch adds a capability to do so by issuing:

$ make print-<myvariable>

e.g.

$ make print-DL_DIR
DL_DIR = /home/evigier/buildroot/dl

Hum, is this really useful? What are the use cases? What do other thinks about this?
