`make TAGS` produces a TAGS that causes the emacs v22.0.92 command 
'M-x tags-search' to repeatedly stop with complaints about missing files.
Proximate cause of this is "#line" directives in Linux source files.

`make tags` produces hundreds of lines of complaints about duplicate
entries.

The following ugly patch works around these problems.  Posting to
both kbuild-devel and emacs-devel in hopes something better can be worked out
for the Emacs v22 release.
