This bug report was about system types, not triplets, but the problem is
kinda similar and equally in need of a fix. :-)

I think it’s “nice” for ‘--target’ to accept a free-form triplet,
because users might want to target a system triplet that Guix
maintainers do not care about (we only cross-build for a handful of
triplets right now).
Based on that, I thought we could emit warnings when ‘cross-gcc’ &
co. were passed a string that doesn’t look like a valid triplet. But
then I realized that internally these procedures are passed things that
are not quite triplets: see avr.scm and embedded.scm.
So, a list of “supported” triplets like you suggest may be a good idea,
though IMO it should be used to emit a warning rather than error out.
For system types, we can probably error out to strings not in the list.
Thoughts?
Ludo’.
