[PATCH 2/3] kbuild: remove unnecessary variable initializaions

From: Masahiro Yamada
Date: Tue Sep 09 2014 - 06:44:14 EST

Clearing obj-y, obj-m, obj-n, obj- in each Makefile is
a useless habit.

They are non-exported variables; therefore they are always empty
whenever descending into each subdirectory.
(Moreorver, obj-y and obj-m are also set to empty at the beginning
of scripts/Makefile.build)
