This makes it possible to provide armv7 as additional architecture in
Alpine, next to armhf. See the discussion in this ML thread:
<https://lists.alpinelinux.org/alpine-devel/6271.html>
It's done by adding armv7 next to armhf in the arch line and also
!armv7 where the arch line said !armhf. The following script was used:
tests: [notice] lvlhsh test started: 2 pool
tests: [alert] lvlhsh test failed: key B469B2CC is already in hash
tests: [notice] lvlhsh add test failed at 1
