[PyQt] sip snapshot problem with PyQwt

Hi Phil, hi Gerard,

in an attempt to build PyQwt with the current sip snapshot (c38668e9dd93), 
sip fails with a strange error:

/usr/bin/sip -I /usr/share/sip/PyQt4 -b tmp-qwt5qt4/qwt5qt4.sbf -c tmp-qwt5qt4  
 -x VendorID -t WS_X11 -x PyQt_NoPrintRangeBug -t Qt_4_7_1 -x Py_v3 -g 
 -x HAS_PYQT_031105 -x HAS_QWT4 -x HAS_QWT_SVG -t Qwt_5_2_0 ../sip/qwt5qt4/QwtModule.sip
sip: No %Module has been specified for module defined in /usr/share/sip/PyQt4/QtSvg/QtSvgmod.sip
SIP failed to generate the C++ code.

The PyQwt package is also a snapshot build, all files are available here:

https://build.opensuse.org/package/files?package=python-qwt5&project=home%3Afrispete%3APyQt-next

The sip files (from PyQt-x11-gpl-snapshot-4.8.2-634f8a2612bf) are installed 
properly and /usr/share/sip/PyQt4/QtSvg/QtSvgmod.sip looks fine to my 
untrained eye:

cat /usr/share/sip/PyQt4/QtSvg/QtSvgmod.sip

OTOH, the rest of the project (including PyKDE4!) is building just fine 
with the current sip and PyQt4 snapshots:

https://build.opensuse.org/project/monitor?project=home%3Afrispete%3APyQt-next

Do you have an idea, what's going wrong or how to debug such an issue? 

It might be Gerards fault, but the error looks pretty strange.

While at it, I noticed, that you added a way to suppress the header 
timestamps in sip. While this is goods news (may loose one ugly patch in 
my builds, that ensures the results of unchanged rebuilds to be exactly
equal). However, in order to make use of this, it is necessary to be able
to specify this option in PyQt4 builds (or even better, globally disable
it in sipconfig.py, unless somebody actively enables it..).
