------------------------------------------------------
Subject: kbuild: obj-dirs is calculated incorrectly if hostprogs-y is defined
From: Pavel Roskin <proski@xxxxxxx>
When Makefile.host is included, $(obj-dirs) is subjected to the addprefix
operation for the second time. Prefix only needs to be added to the newly
added directories, but not to those that came from Makefile.lib.
This causes the build system to create unneeded empty directories in the
build tree when building in a separate directory. For instance,
lib/lib/zlib_inflate is created in the build tree.
