I'm sorry, but I don't understand. If we agree, that "yes both $(CC)
and $(CROSS_COMPILE)gcc are the same", then why would changing one
for the other in above lines make any difference?

Yes, I can see the -mcpu=54455 flag.

But no, I cannot see the "-m5407" string anywhere in your output.

I can see the "m5407" string here; this comes from the PLATFORM_LIBS
variable, which gets set in the Makefile as follows:
# Add GCC lib
PLATFORM_LIBS += -L $(shell dirname `$(CC) $(CFLAGS) -print-libgcc-file-name`)
-lgcc
But here you don't replace the $(CC), so this cannot be the culprit.
Sorry, I do not understand what you are trying to tell me.
