I saw but I am concerned there is more to this. I think INCLUDES is 
specific to automake.

This is a CPP action and not a CC action. This is the root of the 
problem as the CPPFLAGS is not being set.

The include path to the BSP headers is present in CFLAGS but there is no 
CPPFLAGS defined by the RSB and we need to have the path in the 
CPPFLAGS. I have a patch I am testing which adds this. Once the symbols 
issue is resolved and I can test the whole process I will push the change.
