Buildbot runs a new shell for every step (well, not even that - it
only runs a shell if the step has a string for command=; if the
command is a list, it just executes it directly), so there's no sense
of "changing" an environment variable - any such change would be lost
when the shell exited.

You can use buildbot's env dictionary to set environment variables,
but there's currently no way to append to or otherwise "adjust" an
existing environment variable.
