waf, PYTHONHASHSEED & -I order on other architectures

[Michael Tokarev]

Just adding 3 comments to clarify (it is -ENOCOFFEE time).

1. I do set PYTHONHASHSEED=1 now everywhere, including this failing arch

2. complete build logs are available at
  https://buildd.debian.org/status/package.php?p=samba . There, the sparc64
  build failing (Click on the "Build-Attempted" link) exactly due to this
  issue.

3. the "good" version is taken from amd64 build of the same file.

Thanks,
