Subject: [PATCH 1/3] kbuild: remove unnecessary "obj- := dummy.o" trick

From: [email-masked] (Mike Turquette)
Date: Tue, 09 Sep 2014 10:43:37 -0700

Quoting Masahiro Yamada (2014-09-09 03:26:19)
> In these Makefiles, at least one of "obj-y" and "obj-" is non-empty,
> hence built-in.o is always created without such a trick.
