Well I'm still a bit confused about what were they using exactly,
since I'm pretty sure clang has never worked in its upstream form in a
general way from 2012/3. As I said maybe they ship a branch of their
own or something, not sure.

In any case Solaris is not Illumos, so we still need a
solution. Should we add a way to distinguish between them and disable
this feature only for Sun/Oracle Solaris? If they are diverging in
things like this it seems sooner or later it would be needed anyway.
