It's as streamlined as can be:
- make a release tarball on your development machine by running "make
dist"
- run ./configure with --enable-udev-rules=no

Then you can remove

^^^^^^^^^^^^^^^^^^^^^^^^^^

That whole section, because you're building from a tarball

^^^^^^^^^^^^
That work-around, as the file is already in the tarball.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
That hack too.
