Ability to suppress "invalid local symbol" errors

It used to be a warning and became an error in https://github.com/llvm/llvm-project/commit/3ac94280245415be66cb1b603367c5f4f6d498e7

Shared objects are not always in the developers control so there should be at least a way to ignore these errors.
Since it was a warning before there should be a way to complete the linker process successfully, maybe there is a flag already or one could be implemented?

Start with commit 3ac94280245415be66cb1b603367c5f4f6d498e7 and trace how the linker reports "invalid local symbol" errors, comparing that behavior with the earlier warning behavior. Review the related Rust issue for compatibility context. Done means developers can explicitly complete linking successfully when these diagnostics come from shared objects.
