I use the following approach with iscan:

  put SANE customisations to ltmain.sh in a diff (ltmain.sh.diff)
  remove ltmain.sh (and libtool) from CVS (if they are in CVS)
  use a script to "bootstrap" a clean checkout
  apply the patch as part of the bootstrap

This works fine for iscan on a variety of Linux distributions and
versions.  The worst I've seen is a little "complaint" from patch
that the diff applied with a non-zero fuzz factor.

Hope this helps,
