This one on the other hand seems to be a toolchain issue...

rpmbuild calls out to

/usr/lib/rpm/brp-python-bytecompile /usr/bin/python

which basically in this case seems to try to parse python3 code with 
python2 and it falls over...

So I've disabled bytecompiling on kernel builds until I can check the 
toolchain behaviour...
