Remove the recursive check, as it caused an infinite loop. It took a
very long time to complete anyway, even when it worked. The reasoning
for having the recursive check in the first place was, that we would
have device packages with arch=noarch set in the APKBUILD, but which
could only be built for a certain architecture (the device
architecture). Nowadays using arch=noarch in device packages is
forbidden, and we enforce that rule [1]. So the recursive arch check
isn't necessary anymore.
