That doesn't work, since each command is run in a seperate process, and
(unless you pass a string instead of a list) the shell isn't involved at all.

I'll second the suggestion to make the buildbot process reproducible
outside buildbot. But another option is to make the list of environment
variables to set be contained in some sort of easily parsable file
format, and having that parsed by both a shell script and buildbot.
