cnf/configure: use bash instead of sh
Otherwise trnl gets set to "\n" with bash and "" with dash which leads to different behavior depending on the build host, breaking reproducibility.

Followed by a PR "don't use bash" because of course there are people running it with only dash/ash/whatever.

What do you mean by trnl, the value in config.sh? Can you post expected/actual results, and how you're running it?
I'm not getting any difference bash-to-dash. But I'm also getting trnl='tr', so there's probably something else going on.
If I read #87 right, the trnl issue was fixed in a different way in perl-cross long time ago? I might have missed that, then this PR is obsolete.
