As it stands, the patch is only applicable to linux.  On parisc,
kernel support is required to implement GCC's atomic builtins and
linux is the only system with this support.

I have no clue as to whether Qt will build on hpux or openbsd.  If
not, the change could go upstream as is.  Otherwise, we need to keep
the old atomic code for hpux and openbsd.

The patch changes the atomic interface and this affects quite a few
packages using qt4-x11.  Since hppa has been back in ports, we have
been building qt4-x11 unstable with this change.
