Thanks,
Mauro

After thinking a little bit about that, it should be easy to fix the
tool to consider references relative to tools/.*/Documentation.

I intend to send a new patch series with the changes to 
tools/memory-model/README removed from this patch and with the enclosed
patch on it.

Regards,
Mauro

[PATCH] scripts/documentation-file-ref-check: check
 tools/*/Documentation

Some files, like tools/memory-model/README has references to
a Documentation file that is locale to it. Handle references
that are relative to them too.
