A common solution for developers using Linux distributions were
/usr/bin/python is linked to /usr/bin/python3 is to put a python ->
python2 symlink earlier in the PATH when working with python2-only
projects. This doesn't work when shebangs bypasses any environment
configuration.
The change was generated by executing:
sed -i 's|#!/usr/bin/python|#!/usr/bin/env python|' \
$(grep -rl '#!/usr/bin/python' build)
