Nice debugging for a nasty problem.

What about an environment variable that can tell Guile to do the
setlocale().  We can set the environment variable during the build so
that at least the build works, and whisper it to users when they run
into problems (while noting that the variable will not be read in 2.2).

Or should we go ahead and document it, and simply have its default value
change between 2.0 and 2.2?
