AFAIK the target-ARCH? predicates aren't documented, though it could
be useful to document them in the manual somewhere

There is also a (non-applied) patch adjusting package definitions to
use the target-ARCH? predicates: https://issues.guix.gnu.org/49672#9.
(But not target-x86-64?/target-x86-32?, presumably because those aren't
in master.)

Greetings,
