The theory is that it should be convenient to run them when we are
considering a "gettextize" patch.

Maybe something like the following would make it easier for some
people to always build with GETTEXT_POISON and run tests with
GIT_GETTEXT_POISON only occasionally.  I'd rather have a real poison
locale since this would not require any runtime support in the git
binary, though.  Does the value of LC_MESSAGES have to be a valid
locale?  Would something like en_US@poison work?
