Peter Dillinger 0c56fc4d66 Allow missing "unversioned" python, as in CentOS 8 (#6883) ... Summary: RocksDB Makefile was assuming existence of 'python' command, which is not present in CentOS 8. We avoid using 'python' if 'python3' is available. Also added fancy logic to format-diff.sh to make clang-format-diff.py for Python2 work even with Python3 only (as some CentOS 8 FB machines come equipped) Also, now use just 'python3' for PYTHON if not found so that an informative "command not found" error will result rather than something weird. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6883 Test Plan: manually tried some variants, 'make check' on a fresh CentOS 8 machine without 'python' executable or Python2 but with clang-format-diff.py for Python2.
