XCOMM dependency handling for linux, included by linux.cf.
XCOMM We do not want builds to fail if dependencies cannot
XCOMM be generated.  In some cases, checking will always fail
XCOMM because the relevant files have not been generated yet.
XCOMM Not ignoring errors can cause make to go into an infinite
XCOMM loop during depend processing.
