I'm not totally thrilled about having the equivalence between "uclibc"
and "no locale" patched into random sources in a piecemeal way like
this.  uClibc doesn't inherently lack locale support, it's just that the
default oe-core configuration happens to turn it off, and there's no
reason that another layer mightn't decide to enable it again.  It would
suck if that layer then had to re-patch all these recipes to take the
__UCLIBC__ conditional back out.

I think it would be better to replace this sort of thing with an
autoconf linker test that checks to see whether newlocale() is actually
available in the installed libc.
