patch under test

It doesn't seem that the rationale for the changes in r12-35/36 is captured
anywhere I could find - and the commit messages don't contain anything helpful.

This is my current guess at a more complete fix .. I tried it on i686-darwin9
(with an m64 multilib) and x86_64-darwin17 (with an m32 multilib) - but I
haven't tried it on a system with no multilib (e.g. x86_64-darwin20).
