Some export processors (like ox-texinfo) can export to multiple output
formats. A simple defcustom will not cut it because one may want
different link transformations depending on the issued export command.

I am not sure if there is a clean generalized way to implement link
transformations on ox.el level. Individual backends may support this
better.

I guess a possible somewhat generic solution could be adding a new key
to org-export-define-backend and org-export-define-derived-backend.
Specifically for transforming links to other org files.
