[Gianfranco Costamagna]

Hello, this patch [1] based on https://gitlab.freedesktop.org/mesa/mesa/-/commit/3dd299c3d5b88114894ec30d1fac85fba688201f
did the trick.

I'll add as part of my ongoing SRU request.

Bug description:
  [Impact]

  These are needed for 18.04.5 images.

  [Test case]

  Boot a daily image, see that it still has the necessary stack
  installed and working.

  Check upgrade from stock bionic.

  [Regression potential]

  libdrm: very minimal chance for regressions

  llvm-10: a new package, no regression potential on it's own

  libclc: more or less just adds support for new llvm

  mesa: a new major release, but we'll pull the final stable release of
  20.0.x series, so there shouldn't be any regressions left at that
  point

  xserver: a new point-release

  xorg drivers: modest updates, if any

  [Other info]

  mesa and libclc will migrate to llvm-10 in a separate upload
