Comment:
New push:
 - reincluded `fix-math_env_h.patch` in the new version suggested by upstream (https://gitlab.com/embeddable-common-lisp/ecl/-/issues/653#note_675299471)
 - replace the per-arch cross_config files by the 4 different ones `{32,64}{be,le}.conf`. It could also be a template that is substituted in `pre_configure()`, but this seems the easiest way to do it.
 - lint fails just because it doesn't like long lines in the git log message. I will amend.
