From 9870a93d3118239fd7732a0f908e05f67b39a294 Mon Sep 17 00:00:00 2001 From: Pavel Roskin <proski@gnu.org> Date: Thu, 1 Jun 2006 21:28:50 -0400 Subject: [PATCH] kbuild: obj-dirs is calculated incorrectly if hostprogs-y is defined 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.
