Thanks for your valuable feedback. It makes sense that using the default of
64 threads as that matches the limit for related stack arrays in OpenBLAS.
Other distros such as Debian, Arch Linux also build generic package with
hardcoded max number of threads of 64.
Attached is a revised tarball, thanks.
