I didn't noticed that the repository is no longer available because I'm using a
mirror locally: https://github.com/llvm-mirror/libclc.git

If we really care about thee download size, maybe we can use the mirror before
updating to llvm 11.0 that's the first release providing an archive for libclc:

https://github.com/llvm/llvm-project/releases/download/llvmorg-11.0.0/libclc-11.0.0.src.tar.xz

Otherwise ok for me.

Here you're removing the sub-shell but it's used for most other packages.

Best regards,
