[PATCH] udev/libsysfs cross compile fixes

I noticed that libsysfs doesn't inherently grab cross compilation arguments
that are set in the top-level Makefile, so I've come up with the following
patch to fix this. With the patch, I can succesfully cross compile for other
architectures (such as sh) by doing 'make ARCH=sh CROSS=sh-linux-' in the
top-level directory.
