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:
some zstd tests are breaking in ppc64le because it defines the max
number of supported cores as 128 (ZSTDMT_NBTHREADS_MAX 128) but the
Alpine ppc64le machine has 160 cores.
I am increasing the max core value to 256 for now and opened a bug[1]
in zstd project.
