@GrahamcOfBorg build libclc

@athas can you please address the build failure?

I don't know why it's trying to build for aarch64. The targets libclc lists as supported are all NVIDIA and AMD GPU architectures. Is there a way to find out whether the current libclc used to build on aarch64? (It certainly doesn't now - it does not build on anything.)

platforms.x86_64?

If the aarch64 failure is a blocker for 19.09 (note the current libclc does not work at all on any platform), I recommend just disabling aarch64 (no idea how). I have no way to debug it, since I do not have access to an aarch64 machine.

I managed to find an aarch64 machine and fix the issue, I think.

Relevant for #68361.

@GrahamcOfBorg build libclc

@athas please rebase on master and remove the broken bit.

Done!

@athas looks like there are still issues.

Looks like some of my changes got lost in the rebase. Should work now.

@athas looks like something else went wrong with your push: undefined variable 'clang-unwrapped'

Alright, check it out now.

@matthewbauer are you familiar with this library at all? If so... care to take over from here? 😄

Any news here? As stated in the original PR, the current libclc simply doesn't work (and is barely used for anything; my motivation is eventually fixing Mesa), so this cannot possibly go wrong.

Let's re-check the builds.
@GrahamcOfBorg build libclc

It seems a bit suspicious to use wrapped bin/clang++ and unwrapped bin/clang, but if it seems to work, it's surely better than a package that doesn't even build.
