OE uses its own cross building process. You can't encode that cross
building process into those macros. rpmbuild assumes native compiling.
People have tried and concluded its really not practical.

Think about the fact that even if you did have something there, the
original process used to run the build would be different. That means
two different code paths, one of which will probably end up with
different results and hence be broken.

So yes, I understand the desire but it really doesn't make sense.
