Hi,

I just had a look at why python3-hdf5plugin doesn't reproduce and it
seems to capture the CPU features of the host where the build runs and
embeds it in the binary. Could you have a look and avoid it? If it would
actually uses these results, your package would very likely be violating
the Debian baseline for amd64 too.
