[PATCH v3] llvm: enable LLVMgold.so build by adding binutils dependency

[mark.yang]

From: "mark.yang" <mark.yang@lge.com>

Currently, LLVMgold.so is not built because the binutils headers
are missing during the build process.

This allows LLVM to find the necessary headers and build the LLVMgold.so,
which is required for Link Time Optimization (LTO) support properly.

This patch is a Ping.
Details regarding this patch can be found in v1 and v2.

v1: https://lists.openembedded.org/g/openembedded-core/topic/patch_llvm_enable/117252728
v2: https://lists.openembedded.org/g/openembedded-core/topic/patch_v2_llvm_enable/117274480

It was included in master-next but has since been omitted.
Therefore, I am sending a gentle ping.

I don't think my Signed-off-by here is appropriate as I did not sign-off this
version of the patch in particular. I may have picked a previous version of this
patch and applied it to my branch. But when re-sending a patch please the
Signed-off-by list to your identity only.

Thanks!
Antonin
