Ok, here's what I found: The reason that -DQT_SHARED is not added is
because Debian removes the link_prl option from qmake.conf. I guess the
reason is that this is not needed on a debian based system most of the
time.

So adding

CONFIG += link_prl

to qtdirs.pro (don't know wether the file is generated or not) solves
the problem.

I've sent a bugreport to debian asking for a fix, leaving link_prl in is
not an option as that causes other unwanted side-effects (like an
application that uses QtSql module to always link against mysql libs). 

Also I checked Debians pyqt package but the configure.py in that version
(4.2) didn't yet check for QT_SHARED as it seems. Which is why it works
there.
