[Bug 1973076] Re: Missing i?amin_ symbols in libblas-dev:amd64

[Ian Giestas Pauli]

I've looked into the `SRC` code of this package and it seems `i?smin` is
missing there too, so it's not the package's fault. I looks like it is a
common `blas` extension that exists in intel's MKL and other vendors but
it is not implemented in the reference blas implementation.

I'm closing this since there is nothing you can do about it I guess,
thanks for your time anyway.
