While all the other pythons turn of the brp-python-bytecmpile script and bytecompile the files manually by the freshly built binary, python2 apparently just lets brp-python-bytecmpile bytecompile everything with /usr/bin/python2.7. This might bite use some day for the following reason: * pythoon2 now uses python2 during buildtime without buildrequiring it explicitly and things works because it is pulled in transitively * if the bytecode format changes (extremely unlikely, however possible), the build has to be bootstrapped. While I think the severity of this is fairly minimal, I'd like to solve this while looking into bz1570250.
Running brp-python-bytecompile also results in: DEPRECATION WARNING: python2 invoked with /usr/bin/python. Twice at the end of the script.
