FWIW, parisc seems to be the last architecture to keep such thing - sparc and mips had dropped SunOS/Solaris/IRIX compat, iBCS* is long-dead (and hadn't been in mainline kernel anyway). Alpha might still be able to run some OSF binaries, but there the situation is different - no alternative syscall entry codepath, Linux just uses the same ABI and shares syscall numbers where possible...
