Reading https://numpy.org/doc/stable/reference/simd/build-options.html,
I do not think setting disable_optimization to true by defailt is
correct. Currently, numpy will auto-detect the capabilities of target
machine, and configure itself accordingly. With this change, that auto
detection is compeltely turned off.
Please explain the rationale for this change.
In our case, we use `-cpu kvm64' other than `-cpu Skylake-Client
-machine q35,i8042=off'
QB_CPU_KVM:intel-x86-64 = "-cpu kvm64"
If that cpu doesn't support v3 (or even v2) features, then you should
not use the default x86-64 tune (that qemux86-64 is using and passing
to compilers) to enable them.
Sure, already did, thanks for pointing it out, please drop this patch
