Subject: [PATCH] Fix Makefile.modbuild to delete Makefiles on distclean,
 CFLAGS not to duplicate kernel flags. Fix scripts/dep.* to not add to CFLAGS
 if the RTAI/RTLinux include directories don't exist.  (Might not be an error
 -- otherwise it's difficult to compile for a real-time patched kernel without
 the RTAI/RTLinux source.)
