It'd really better be short-term, because currently we cannot really
trust the built packages: what if due to shell script misbehavior
./configure misdetects features, forgets enabling some support
etc. That'd lead to subtle incompatibilities that'll be hard to hunt
down.

Don't take me wrong: I'm not saying the concern is *because* of bash,
but *concerning* bash. Another shell could very well just face exactly
the same concerns.

And no, we cannot just switch it: libtool uses the bash features, so we
have to fix the behavior of the system for bash (and /bin/sh already
points to dash)
