linked against musl, and what musl version is used.

�S )a` Detect currently-running musl runtime version.
This is done by checking the specified executable's dynamic linking
information, and invoking the loader to parse its output for a version
string. If the loader is musl, the output would be something like::
musl libc (x86_64)
Version 1.2.2

:param arch: Should be the part of platform tag after the ``linux_``
prefix, e.g. ``x86_64``. The ``linux_`` prefix is assumed as a
prerequisite for the current platform to be musllinux-compatible.
:returns: An iterator of compatible musllinux tags.
