f$ r Y yw xY w)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 archs: Sequence of compatible architectures.
The first one shall be the closest to the actual architecture and 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.
