Why would such a rename be needed?

The linker scripts aready get preprocessed, even without this rename.
See the rule

 369 $(obj)u-boot.lds: $(LDSCRIPT)
 370                 $(CPP) $(CPPFLAGS) $(LDPPFLAGS) -ansi -D__ASSEMBLY__ -P - <$^ >$@

in the top level Makefile.

Best regards,

Wolfgang Denk
