I guess the problem is that, whilst we *could* arrange to allow PIC to
be switched off for x86-64 darwin, it is not supported by the system,
which could open up a different can of worms with Users trying
something that is bound to fail....
so what about this as a compromise -
- the test that Jakub identifies as not particularly strong is only
applied to Darwin
- for which it would seem to check the output adequately.
does this work elsewhere?
