...you're on your own I think.

The qtdirs utility is built using your Qt's qmake. configure.py isn't doing
any special at that point, so I suspect you might have similar problems
with any C++ code.

You could try running qmake manually on the qtdirs.pro file that
configure.py will have left lying around, and then run make, and then the
qtdirs it produces.  If it fails to run then it's a problem with your Qt
build.
