Never mind, this was a stupid idea -- bash in POSIX mode continues to set
BASHOPTS under `env -i`, so this buys us nothing.

New idea: Terminal allows passing in an environment directly, which is
currently unused. What if we passed the execution environment in through
that, instead of encoding it into the script?

(Yes, this probably belongs in oe-core more than bitbake-devel at this
point...)
