In 70efb00e59f5971511232965497edfbf83d848ac we do the following.
Allow ELF subtargets in subtarget-independent code.
For static materialization case, implement ELF auth stubs similar to MachO ones: wrapper symbols like sym$auth_ptr$AUTH(key,discr) holding relocations to be resolved in dynamic link time. These stubs are mostly identical to MachO ones, so most code is shared.
Implement tests for lowering in case of ELF subtargets.
