Figured that was python3 only code, adding a #ifdef (patch appended).

Now, hit 'make install' failure, seems to expect mk_distinfo.py to exist,

/usr/bin/python3 mk_distinfo.py /usr/lib64/python3.6/site-
packages/sip-4.19.9.dev1805261119.dist-info installed.txt
/usr/bin/python3: can't open file 'mk_distinfo.py': [Errno 2] No such file 
or directory
