From 283af72cd819c32f7fe6a182f06fecb7dfa00bb8 Mon Sep 17 00:00:00 2001

Subject: [PATCH] For separate kernel source and build directories, allow the
 kernel build directory's Makefile to specify KERNELSRC using a relative path.
 This avoids having to use the --with-kernelsrcdir option when configuring
 Comedi for SuSE Linux's kernels.
