It seems to me that patch(1) should just recognize and handle this
situation. The correct behavior is obvious - accept CRLF and LF (and
CR) line endings, apply the transformation preserving the current
line-ending format of the target file. Diffs do not work on binary
files anyway.

You could also consider this a special case of Karl (IIRC)'s
intelligent patch-merging algorithm.
