here. Sorry for the confusion, and yes both $(CC) and $(CROSS_COMPILE)gcc are the same. It is unsolvable behavior in ifeq (...) where $(shell $(CC) --version) does not match 4.2 and caused linking error.
Original: ifeq ($(findstring 4.2,$(shell $(CC) --version)),4.2) PLATFORM_CPPFLAGS += -mcpu=54455 -fPIC else PLATFORM_CPPFLAGS += -m5407 -fPIC endif
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?
As you can see below captured, -mcpu=54455 was selected in compiling when gcc version is 4.2. When it comes to linking, the $(shell $(CC)
Yes, I can see the -mcpu=54455 flag.
--version) becomes other value and select the -m5407 option with different libgcc.
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.
