This is not really a great title. A better title IMO could be:

	Fix building with locale support

> +Locale support in ilixi is a conditional dependency, and is only used when the libwnn dependency is also met. 

This should be wrapped to 80 characters. And you need to Signed-off-by
your patches.

Also, please submit this patch upstream.

Not related to the review itself, but I find it odd to use things based
on DirectFB these days. The project is dead, the web site has been dead
for over a year now, etc.

We typically don't indent the \

This last \ is not needed.

The sawman package no longer exists in Buildroot. Please make sure to
send your patch against the latest version of Buildroot. Sawman is now
part of DirectFB itself.

Does ilixi has some optional dependencies? According to your patch, it
can optional depend on libwnn. If that's the case, then please add the
relevant --disable-<foo> or --without-<bar> configuration options to
explicitly disable all those optional dependencies.

Thanks!
