At the very least, lld is pretty much drop-in. Aside from some subtle differences about resolution order (IIRC lld implicitly has "--start-group"/"--end-group"), everything just works with lld in place of ld.bfd. My recollection was that I had just about the same experience w/gold -- it was just a drop-in replacement. All of my experience was with using clang as the driver, so I can't speak to why gcc has trouble making a similar feature work like expected.
