David is correct.

The RTL was championed by Lou Infeld at Apple, who also implemented the
original version of the Loader. It is my understanding that the loader
supports RTL files. The loader was, however, heavily modified later to make
it faster, and I have no idea of the people doing the modifications cared
about Lou's pet.

Lou also wrote Link IIGS (the Mac version for MPW), and I heard that this
linker supported RTL files.

None of the ORCA languages ever used them. I don't know of anyone who ever
did actually implement one. They were, after all, both unneeded and
technically inferior to user tools, which do the same thing and do it
better.
