[Wheel-builders] Wheel files for PPC64le

[Nathaniel Smith]

Hi Leonardo,

Yeah, you'll need to write a PEP. PEP 513 is the spec for i686/x86_64,
and should give you some idea of what to expect:

    https://www.python.org/dev/peps/pep-0513/

Yours might be much shorter, depending on how much stuff you can
hand-wave with "see PEP 513" :-).

Writing a PEP isn't too hard -- see:

    https://www.python.org/dev/peps/pep-0001/
    https://www.python.org/dev/peps/pep-0012/

The standard list for discussing packaging-related PEPs is actually
distutils-sig, not wheel-builders, so you'll want to move discussion
over there going forward.

The main technical issue here is that you'll want to have a somewhat
convincing story for (a) how to build packages that will be compatible
across a reasonable range of systems, (b) some way for pip to decide
whether it's running on one of those systems that your packages will
work on. I don't know enough about PPC64le to guess what this will
look like, but you can see PEP 513 for how we did it there.

A bonus would be if you have some nice story for how end-users can
actually build these packages, like the manylinux docker image. But
the manylinux docker image itself assumes the existence of
infrastructure like Travis-CI, which is not really something that
exists for ppc64le, I think. I guess you could try running docker in
qemu on travis :-).
