To better describe our use case, we're porting an existing embedded project from GCC/ld to Clang/LLD and this is one of the differences we encountered. We can still link the targets, but it results in a lot of noise; hundreds of these messages in a full build. Unfortunately, the issue originates in third party driver code that was supplied by an external vendor and it's not something we can easily address.

We're open to other suggestions, but we believe that other LLD users working in the embedded domain might eventually encounter this issue as well and having an option to suppress this warning might be helpful.
