libclc is required in order to build Intel drivers in Mesa 24.1 and
later. Thus OE-Core is currently locked to the 24.0.x branch, which is
no longer maintained, having last release in June 2024.

A clean solution is to package Clang, then use it to build libclc and
SPIRV-LLVM-Translator (required for Mesa OpenCL support). However
creating proper recipes for Clang is a long process (ongoing by Khem
Raj).

This patchset attempts to solve the issue in a simpler way: by building
libclc and SPIRV-LLVM-Translator together with the LLVM. This way we
don't have to create target Clang recipes, there is no extra toolchain
to support, etc. Clang binaries are creted as a part of the build
process (in order to support building target packages), however it only
hits the LLVM sysroot-native and is only used by the LLVM target build.

Future work by Khem (once Clang is properly supported in OE-Core) should
allow us to create proper recipes for libclc and spirv-llvm-translator
and drop them from the llvm / clang recipe.

I think this approach provides a good balance between OE-Core being
stuck with the outdated Mesa release and being able to upgrade it,
bringing support for new hardware.

Last two patches of the series bring in RustiCL support, a new OpenCL
implementation within Mesa. They are optional for the sake of the
upgrade and can be dropped if there is any issue with those. RustiCL
support is mostly compile-tested at this point.

I like the approach, but I don't particularly like the volume and
amount of 'Inappropriate' patches this set brings in. This will
complicate future maintenance, and particularly version updates.

In addition to what Ross said, can you see what can be reworked for
upstream submission, and what can be at least reported to upstream?

I have reworked the patch to use prefix+libdir instead of 
LLVM_LIBRARY_DIR, but I'll investigate if we can drop that completely in 
favour of reporting a correct libdir from llvm-config script.

Other than that, I'll ping Karol regarding the bindgen invocation hacks.
