Seems like those arches are not supported, please disable them with `!arch` in the `arch=` variable

I had a quick look around, and found that Fedora applies some downstream
patches to get hdf4 compiling on s390 and various ARM processes:
https://src.fedoraproject.org/rpms/hdf/tree/rawhide  We could consider
including some of these to see if it allows the build to succeed
instead.

If we were to do this, what would be the process to bring these patch
files in?  We could source them from Fedora, or have them included
locally.

Also, is there a way for me to test out whether this causes the builds
to succeed without resubmitting patches repeatedly?  I don't have access
to all the necessary hardware to do it all my end, and I'd ideally like
to submit some builds directly to the servers.

Please add them locally and just resubmit the patchset/merge request. CI will take care of seeing if it builds on those arches

Sorry to bother you @mailinglist-bot,

but we've detected that this merge request hasn't seen any recent activity. If you need help or want to discuss your approach with developers you can ping `@team/mentors`. You can also ask on IRC on `#alpine-devel` on irc.oftc.net. If no further activity occurs in this MR, Alpine developers may close it in the future.

Thanks for your contribution.
