The description below is a quote from Brian Masney in #296.
The pmOS mesa packages need to have -Db_ndebug=true passed to the meson
build so that debug assertions and extra validations are disabled to
improve overall system performance. See [1] for more details. Fedora
also recently made this change: [2]
This change, along with using the master branch of mesa, gets the
Freedreno driver working properly with X11 on the Nexus 5 and presumably
other A3XX-based systems.
--buildtype=release should also be passed to meson for extra
optimizations. See the thread [3] for more details.

[ci:skip-build]: already built successfully in CI
Remove Alpine's maintainers and contributors from the APKBUILDs in temp
where we still had them. In general, we don't keep them there, because
we don't want them to get e-mailed about questions from the postmarketOS
aports. It is obvious that they were copy pasted from Alpine, with minor
adjustments.
Remove "Remember to increase pkgrel after changing _pkgver!" from
temp/mesa, because we have a CI check for that now.
[ci:skip-build]: cosmetic changes only
Fix the regression from the mesa refactoring and from switching to armv7
in hammerhead.
[ci:skip-build]: already built successfully in CI for x86_64; I've
tested manually that it builds for armv7.
Fix missing symlink for the first driver in mv_dri() (caused by "shift"
at the wrong position). Build freedreno for arm only, not for all
arches.
Lima is for rendering and sun4i-drm (part of kmsro) for the display, so
split it into its own subpackage and use it in device-pine-*.
[ci:skip-build]: ollieparanoid made sure, that this builds. This won't
finish in time in CI.
Fix up for !359: the pkgrel was not bumped, and because the real mesa
version was stored in _pkgver instead of pkgver (which is set to 9999),
this means that the APKBUILD has exactly the same version as before. So
pmbootstrap will not try to build it, resulting in a missing
mesa-dri-lima package and general confusion.

This updates the PKGBUILD to build tags instead of the release branch
(which will see commits until the specific release is EOL),
This commit also adds building the mesa-xatracker package.

This adds a Mesa package overriding Mesa in Alpine, and:
1) builds a much newer version of Mesa than what is found in Alpine (by
*not* building amd/radeonsi support, so no dependency on llvm).
2) builds Mesa with tegra and etnaviv drivers (note, as of now, the
librem5 devkit gpu is not supported in the etnaviv driver here)
This breaks "pmbootstrap qemu" for some people, use --host-qemu as
workaround for now (a fix will be available soon):
https://wiki.postmarketos.org/wiki/Troubleshooting:QEMU#Using_QEMU_from_the_host_system
Since this also fixes the blackscreen bug on lg-hammerhead, the
trade-off with the qemu bug is worth it.
