I think that depends on how they push the return pointer. I'll see if
I can find out which processors have the feature.
In testing, I have noted one further complication regarding sibcalls
on hppa64-hpux. If you build and install a compiler using the HP
linker and then try to do a bootstrap using the GNU linker, the build
will fail unless sibcalls are disabled because of the poor placement
of stubs using the GNU linker.
