Add "sun4i-drm_dri.so" to libg1-mesa-dri and fix compilation on riscv64

The attached debdiff enables building the lima driver on riscv64. This drivers provides sun4i-drm_dri.so.

I'm currently testing this locally and waiting on riscv64 to be enabled for my PPA to build a package on LP.

The attachment "mesa-build-lima-on-riscv64.debdiff" seems to be a debdiff. The ubuntu-sponsors team has been subscribed to the bug report so that they can review and hopefully sponsor the debdiff. If the attachment isn't a patch, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are member of the ~ubuntu-sponsors, unsubscribe the team.

Matches this bug from Debian: https://<email address hidden>/msg139710.html

The attached patch disables usage of LLVM JIT on riscv64, which was causing the error I reported in comment #3.

I obtained this patch from the following Debian bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1004039

This patch, combined with the previous one, seems to work well on the Sipeed Lichee RV board. I have tested this with ubuntu-frame and a custom-built mesa-core20 snap containing the drivers built using these patches.

Prebuilt packages for riscv64 are available in this PPA: https://launchpad.net/~itrue/+archive/ubuntu/mesa-riscv64

This bug was fixed in the package mesa - 22.2.4-1ubuntu1

Hello Isaac, or anyone else affected,

Accepted mesa into kinetic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/mesa/22.2.5-0ubuntu0.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-kinetic to verification-done-kinetic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-kinetic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

All autopkgtests for the newly accepted mesa (22.2.5-0ubuntu0.1) for kinetic have finished running.
The following regressions have been reported in tests triggered by the package:

mutter/43.0-1ubuntu4 (amd64)

Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1].

Thank you!

Isaac, care to test kinetic that everything is in place now? This is blocking the mesa update.
