ok, i missed that aspect.  i think the changes needed are:

lib_blackfin/Makefile:
	-$(obj)u-boot.lds: u-boot.lds.S
	-   $(CPP) $(CPPFLAGS) -D__ASSEMBLY__ -P $^ > $@
lib_blackfin/config.mk:
	-LDSCRIPT = $(obj)lib_$(ARCH)/u-boot.lds
	+LDSCRIPT = $(obj)lib_$(ARCH)/u-boot.lds.S

i can post a patch once yours gets merged
