Well, obviously folks who do have it in the host environment can set
ASSUME_PROVIDED.  I assume most people do have that installed, otherwise
this would be failing all the time.

Other than that, I think your options are:

1. figure out a way to defer catalog building to later, e.g. put it in
eglibc-locale instead.  This would probably involve some hacking of the
eglibc makefiles but I don't think it would be especially hard.

2. find a way to disable catalog generation entirely for folks who don't
want it.  That might involve inventing DISTRO_FEATURES="l10n" or
something and patching (albeit trivial) to both configure.in and the
makefiles.  I imagine that change would be upstreamable in eglibc.

3. reimplement msgcat as a python script or something else that doesn't
need compiling, or pull out msgcat.c into its own recipe that just
builds this single file (avoiding the autotools overhead that
gettext-native has).

I can't think of any other obvious choices offhand but I'm sure there
are more.

The thing that does seem a bit puzzling is that this problem didn't use
to happen with older versions of oe-core (in particular, I never saw it
with my previous snapshot which used eglibc 2.16).  I'm not quite sure
what changed to make it suddenly become an issue.
