Build for latest OpenBLAS

[mattip]

@tylerjereddy in order to build this repo for a particular OpenBLAS commit, you can make a PR to this repo with an updated OprnBLAS commit hash. There are three places that need to change, grep for COMMIT in the .travis* and .github/* files

Merging that should upload tarballs to the usual places, ready for download by the scipy script (after making a change in that script to match)

Won't it have to be like #145, and no merging, because we can't consume the new wheels yet?

[mattip]

Kind of, base it off the scipy branch and target that branch in the pr

[mattip]

On top of #147

Closing, as the 0.3.27 tarballs for SciPy were built.
