[PATCH 0/7] configure: fix misc shellcheck warnings

[Peter Maydell]

Currently if you run shellcheck on our configure script it
generates a ton of warnings. This patchset fixes some of the
easier ones. I wasn't aiming for completeness or consistency;
I just wanted to zap some of the ones where the fix is clear
and didn't take long to write and is hopefully easy to review.
We can always come back and take another swing at it later.

thanks
