ubuntu-drivers-common now pulls in build tools on end-user systems

This should be fixed before 20.04.1, so we don't install compilers on user system by default.

you may have already done this analysis, Alberto, but fwiw what I see is that dpkg-architecture is used at runtime to get the multiarch path - however, this is always called in the context of the native architecture, so this can instead be calculated at build-time and embedded in the binary since this is in an arch-dependent package. That would solve the problem of needing dpkg-dev at runtime.

Steve: I already have a commit that gets rid of dpkg-architecture, and removes the dependency.

This bug was fixed in the package ubuntu-drivers-common - 1:0.8.4

---------------
ubuntu-drivers-common (1:0.8.4) groovy; urgency=medium

  * ubuntu-drivers:
    - Rework the argument parser.
  * debian/control:
    - Depend on python3-click.
    - Drop dependency on dpkg-dev (LP: #1880564).
  * Add support for the "Support" field in packages.
  * Add support for passing in driver and vendor for
    the "install" case (LP: #1881586).
  * gpu-manager.c:
    - Add get_system_architecture().

An upload of ubuntu-drivers-common to focal-proposed has been rejected from the upload queue for the following reason: "SRU information is still missing for multiple changes claimed in your changelog entries. Regression discussion is still missing in the bugs in which you do have some SRU information. Please follow ALL of https://wiki.ubuntu.com/StableReleaseUpdates#Procedure, or if that is not possible, please explain in the relevant bugs why an exception is warranted.".

For example: where is the SRU bug and documentation related to this change?

   * ubuntu-drivers:
     - Rework the argument parser.
     - Do not print an error when linux-modules cannot
       be found.
     - Add support for the new -server NVIDIA drivers.

@Robie:

1) "Do not print an error when linux-modules cannot be found"
This prevents the ubuntu-drivers tools from being misleading, hoping that people won't file bug reports such as LP: #1882402

2) "Rework the argument parser." - This is a feature that was requested by the Foundations team. It makes the "install" behave consistently with or without "--gpgpu" parameter is used (i.e. you can pass in the driver that you need, as an option). For example "ubuntu-drivers install" did not accept any extra arguments, whereas "ubuntu-drivers install --gpgpu" (e.g. ubuntu-drivers install --gpgpu nvidia) did. Now both do.

I am fine having one more bug report about it, but I'd rather not have to follow many bug reports for the same SRU, if possible.

3) "Add support for the new -server NVIDIA drivers" - it's LP: #1881586

      (LP: #1881586).
  * debian/control:
    - Depend on python3-click (for the argument
      parsing code).
