OS X should support the original names, like en_GB, and it should have
its locale set to that already.

Where did you get your Hunspell binary for Windows?  The above works
for me, so I suspect your Hunspell is subtly broken.

Does that happen in "emacs -Q" as well?  If not, have another look at
your Hunspell- and ispell-related customizations.

On Posix platforms (including OS X), the locale setting should do
that.  On Windows, use one of the 2 methods I suggested, they do work
provided that Hunspell has its known bugs fixed.
