I'm suggesting to use it for testing that the new config is portable
to other systems that provide the POSIX 2008 APIs.

We wouldn't want to use it by default, because POSIX doesn't provide
strtod_l etc that glibc provides. But maybe the "gnu" model should use
newlocale and uselocale instead of __newlocale etc. so that we depend
on fewer GNU extensions that are only defined with _GNU_SOURCE.
