As a Linux Python dev, even if I've sort of learned what "manylinux"
means (not least of all from following these discussions :p), I would
much prefer the "linux_glibc_2_12_x86_64" style tag. It's nice and
explicit and conveys some info, and sort of follows the same style as
the macOS ones.

Just my 2 cents.
