 Unfortunately I think this is unavoidable. But these files can indeed be
just deleted or simply ignored (I already have them in my .git/info/exclude
but they could be added to .gitignore instead).

 The idea would be to use relative path to the script, if we included it
in lmi itself.

 Sorry, I should have mentioned that you need to run automake with the
--copy option if you intend to commit it.

 Again, if you include the script in lmi repository, you could rely on

        $ ./some-subdirectory/config.guess

to work (where "some-subdirectory" could be "build-aux" or
"third_party/aux" or whatever else).
