Do not run qtdetail

qtdetail is a tool that generates qtdetail.out. Since this program is
cross-compiled, it's not possible to run it on the host.

Consequently, python-pyqt.mk generates the qtdetail.out file before
calling configure-ng.py.

Therefore, this patch makes sure that the pre-generated qtdetail.out
file is kept, and that qtdetail is not executed.
