Hello Ludovic,

thanks for the feedback.

I tried to fix the patch and got some promising results.  Please find
the updated patch attached.

Basically I patched 'blis/benchmark.py' to use "blas_opt_info" instead
of "blas_ilp64_opt_info" and tests went fine.  An issue with different
numpy versions I guess?  I also added "blis" and "python-numpy-next" to
the "native-inputs".
