That's right - main makefile for python bindings (python/Makefile) is
generated from CMake. But makefiles which build python bindings should
be python/core/Makefile and python/gui/Makefile - something had to go
wrong if they don't exist. But then I don't understand this:

Which looks like python/core/Makefile exists...

libqgis_core.so is built by src/core/Makefile.

Out of source builds are mentioned on wiki:
Basically it means that all build related files (configuration,
makefiles, generated files, output files) are in a separate directory.
