due to asm weak function link overwrite problem use pre-built object instead of library.
You will need to build the lib$(BOARD).a the same way
Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD plagnioj@jcrosoft.com --- The asm weak overwrite link problem have been found also present on other arm And supposed on other arch
the the AR do not use the $(ARFLAGS) because in this case we will have no file as param to generate the library
