bug#52040: opam importer: unexpected “available: arch != "x86_32"“

[zimoun]

Hi,

--8<---------------cut here---------------start------------->8---
$ guix import opam biocaml
guix import: error: failed to download meta-data for package 'biocaml'
--8<---------------cut here---------------end--------------->8---

This package is defined on OPAM [1].  The issue is the field:

        Available       arch != "x86_32" & arch != "arm32"

format known by the importer/parser but unexpected.  Therefore, it
raises an error and fails.
