It is great that there is now beta support for - os: linux-ppc64le
& we are using this productively in the NumPy development repo.
However, when I try to do debug work in my own fork, which instead uses the GitHub / Travis app & travis-ci.com unstead of older travis-ci.org infrastructure, it seems that the linux-ppc64le
mouseover shows up in the matrix, but the architecture of the provisioned node is actually x86-64.
See the example PR here, which demonstrates the silent switch from ppc64le to x86-64: https://github.com/tylerjereddy/numpy/pull/6
