[PATCH] D138221: [HIP] Fix lld failure when devie object is empty

MaskRay added a comment.

> Some host relocatable objects may not contain device relocatable objects, where an empty file is passed to lld, which causes lld to fail.

How is an empty file (size=0) passed to lld? If a dummy relocatable object file is parsed to lld, lld can infer the machine type from `e_machine` in the ELF header.
