What happens with GNU ld?  It sure looks like you're ending up with the
wrong set of system libraries due to the mix of tools involved.  Oddly
enough, it looks like you've been here before:

http://gcc.gnu.org/ml/gcc-help/2011-05/msg00245.html

and that the Qt documentation says that for 4.8, they don't even bother
trying on Solaris.  (With 4.7, they at least seem to have compiled with
Sun Studio 12, not gcc.)

It's not necessarily Solaris.  Qt/C++/gcc have been giving other people
fits as well:

http://forums.gentoo.org/viewtopic-t-395044-start-0-postdays-0-postorder-asc-highlight-.html

and even without Qt involved:

Google's filled with tons of references to this sort of incompatibility,
but is rather sparse on fixes.

I guess the good part about open source is that when it breaks, you get
to keep both pieces.
