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.
