Guile can cross-build scheme scripts, but if you try to cross-build scheme for
arm or arm64, it fails:

This turns out to be because the runtime detection of endianness in
the build-arch version of the guile compiler is broken. The code is
horrible and tries a lot of dubious substring matching on the host
triplet in order to decide the endianness and word size. This is going
to go wrong in all sorts of circumstances, and should really use a
more robust mechanism such as dpkg-architecture (but that would depend
on dpkg-dev, which might not be ideal).
Anyway I have added arm and aarch64 (arm64) to the substring search
which will, at least on debian produce working results.
This has been tested and guile can now cross-build itself for armhf,
fixing the above error.
Patch attached.

+Description: Correctly find endianness on arm and arm64/aarch64
+ The guile runtime detection of the arch using the triplet is
+ a really bad plan, and this patch is horrible, but it does at
+ least mean that the arches are detected and not just 'unknown'
+ We should really use dpkg-architecture to get it right under all circs
+ but that means depending on dpkg-dev, which might be a problem.
