GLPK 4.65 was released recently and it prints the warning "Long-step dual simplex will be used" all over the place, leading to many failing sagemath doctests in Debian (they fixed it by backporting
an upstream patch)

We backport the corresponding patch to GLPK 4.65.
Having this in will have the tack of #28459 easier.

Upstream: Fixed upstream, but not in a stable release.
