The host versions shouldn't be visible in Kconfig, so remove the
reference to BR2_PACKAGE_PKGCONFIG everywhere and prefix the host targets
with host-.
At the same time add pkgconfig for the target (E.G. for development) and
let BR2_PACKAGE_PKGCONFIG control that package.
Notice: all defconfigs in the tree have been updated, but make sure to
disable the pkgconfig package (unless you want it) if you use an external
config, otherwise you'll end up with pkgconfig and glib2 in the target.
"target/device/Atmel/arch-avre/kernel-headers-2.6.28.2"
Make sure BR2_KERNEL_HEADERS_PATCH_DIR is enabled for 2.6.28
Set
KERNEL_HEADERS_PATCH_DIR="target/device/Atmel/arch-avre/kernel-headers-2.6.28.2"
for Atmel AVR32 targets and "valka"
Mark empty directories in target skeletons with .empty files
and remove them while copying to target (like it's already done for
svn and cvs files) to better support version control system which don't
handle empty directories (E.G. git-svn).
