[ptxdist] [PATCH] udev: Use ptxdist kernel headers
From: Bernhard Walle wa...@corscience.de
When a toolchain without kernel headers (such as the Lite version from

because videodev.h is missing.
This patch adds the $(KERNEL_HEADERS_INCLUDE_DIR) to the include path of
udev like it's done for busybox or barebox.
Tested on ARM with kernel headers 2.6.36.4 (the version
OSELAS.Toolchain() is currently using).
