Reported upstream at https://github.com/KhronosGroup/glslang/issues/3799;
I'm not happy with the patch, and I feel like it can be better, but it
works and it unblocks Vulkan for beta6.

This integrates a patch that is currently sitting upstream in review.
Adding this patch corrects the tools to work on cross-endian binaries,
i.e. a big-endian system can handle little-endian shaders, and vis versa.

user/mesa is the latest (24.2.7), and should install everywhere.
user/mesa-be includes 24.1.7 which is needed for proper operation on
big endian platforms, hence it is only enabled for ppc/ppc64.

* Unfortunately, Intel Iris is not portable due to OpenCL issues and
  cannot be included with beta6.

* The glvnd JSON file needs to be kept with the driver.

* We can't split GL any more, so don't bother.

* The DRI driver depends on the GLX stub, which is part of mesa, so
  declare that dep explicitly.  (weak linked, so abuild can't see it)

Required for the Rust bits of Mesa's new NV Vulkan driver.

This provides graphics drivers for r100/r200 Radeons, and also
early GeForces via nouveau dri.  nv30+ are handled by Gallium.
Uses libglvnd so it can coexist with newer Mesa versions.

Needed for newer Mesa releases.

Needed for new Mesa, and provides AVC1 decoding on supported hw.

This package allows us to ship Amber and current Mesa at the same time.

Also updates the test patch to be applicable to all tests.  This patch
has been submitted upstream and the upstream URL is included.

hwids is an abandoned project. It is now superseded by hwdata which is
more complete.
