One more question about Blas: I have a "Kaby Lake R" mobile

according to Wikipedia, but gretl's $sysinfo tells me something about
blascore=haswell. If I understand https://github.com/xianyi/OpenBLAS
correctly, there are some more supported features like AVX512 starting
in Skylake (the generation before Kaby Lake). So would it make sense for
gretl to target skylake if available?
In OpenBLAS there is no such mircokernel: you have HASWELL for haswell,
skylake and most of the kaby lake CPUs and you have SKYLAKEX (with
AVX512) for skylake-x (they have "X" at the and of the name).
