This is a known problem. platform_setup.h gets pulled into the
vectors.S file. However this is a special file. The code in this file
has to be at the beginning of the image. All the other code gets put
into a library and is then linked to the image. The header file
dependency checking works OK for the library, but not for
vectors.S. So your vectors.s was not recompiled.

rm insall/lib/vectors*

and then rebuild.
