:param format_control: A FormatControl object or None. Used to control
the selection of source packages / binary packages when consulting
the index and links.
:param platform: A string or None. If None, searches for packages
that are supported by the current system. Otherwise, will find
packages that can be built on the platform passed in. These
packages will only be downloaded for distribution: they will
not be built locally.
:param versions: A list of strings or None. This is passed directly
to pep425tags.py in the get_supported() method.

Function used to generate link sort key for link tuples.
The greater the return value, the more preferred it is.
If not finding wheels, then sorted by version only.
If finding wheels, then the sort order is by version, then:
1. existing installs
2. wheels ordered via Wheel.support_index_min(self.valid_tags)
3. source archives
Note: it was considered to embed this logic into the Link
comparison operators, but then different sdist links
with the same version, would have to be considered equal
sB %s is not a supported wheel for this platform. It can't be sorted.(
