Yeah.  In practice, there are exactly two cases we care about: either
both of these functions will be declared in <stdlib.h> like POSIX
says, or both of them will be in <xlocale.h>.  There's no need to
work harder than we have to do to figure that out.

I'm totally unimpressed with the proposal of depending on the __FreeBSD__
macro instead of having a proper configure check.  For one thing, we
have no idea whether NetBSD or OpenBSD have this same issue.  For
another, it might be version-specific, or might become so if FreeBSD
decides to start following POSIX on this point someday.
