All configuration for build of PyQGIS is in python/configure.py.in
(which is processed by CMake). As you correctly figured out already,
the flags come from sipconfig.ModuleMakefile.

Am I right that the problem applies only to bindings (based on
SIP/PyQt4), while implementation of embedded python (libqgispython) is
okay?
