Andreas Schwab has created a bug entry for this issue, using awk or shell should be fine to get the same functionality, but it might take some time, so I plan to add some checking to detect python, python2 or python3, and skip this step if none of above is found. The arch string canonicalize is not a must, it's a kind of improvement, trying to reduce the build # of multi-lib, so I think skip that should not be a problem if python is not available.
