kbuild: clean-up and bug fix of scripts/Makefile.host
Assume we have a Makefile like this:
hostprogs-y := foo
foo-cxxobjs := bar/baz.o
foo-objs := qux/quux.o
In this case, Kbuild creates bar/ directory,
but fails to create qux/ directory.
This commit re-writes directory creation more simply,
fixing that bug.
