From 97e3226e6e984c8cd9bed47010f30827a3ce816a Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 19 Aug 2014 16:34:21 +0900 Subject: [PATCH] kbuild: handle the dependency of multi-objs hostprogs appropriately Assume we have a Makefile like: hostprogs-y := foo bar foo-objs := foo1.o foo2.o bar-objs := bar1.o bar2.o Without this commit, the host program foo depends on all of foo1.o foo2.o bar1.o bar2.o. This commit allows to handle the dependency of each host program separately.
