In a twist of irony, Python manylinux1 wheels assume glibc and so
any with C extensions are unusable with Alpine's musl. As a result,
we'll likely need to cross-compile any of our non-pure-Python
dependencies from sdist/source with an appropriate toolchain and
inject them into image.

The bindep tool does at least have support for Alpine now, so as
long as there are packages available for our system dependencies
that should hopefully be a viable option.
