summary:

[3.12] gh-104692: Include commoninstall as a prerequisite for bininstall (GH-104693) (#105428)

This ensures that `commoninstall` is completed before `bininstall` is
started when parallel builds are used (`make -j install`), and so the
`python3` symlink is only installed after all standard library modules
are installed.

(cherry picked from commit 990cb3676c2edb7e5787372d6cbe360a73367f4c)
