I see it is libx11-native do_configure failure, and the xcb-native is 
missing. that make sense because xcb recipes does not have BBCLASSEXTEND 
= "native nativesdk", thus xcb is not built for native.

I have tried to add BBCLASSEXTEND = "native" in xcb recipe, it turn out 
requiring more dependent recipes to be built for native, which is a bit 
way too far and undesirable.

so let's try another way, since you only care about the runtime libx11 
with xcb support, how about the following patches, with which only 
native disable xcb, and the runtime libx11 will have xcb support.
