Move cc-option to below arch-specific setup
commit d0115552cdb0b4d4146975889fee2e9355515c4b upstream.
Sam Ravnborg says:
"We have several architectures that plays strange games with $(CC) and
$(CROSS_COMPILE).
So we need to postpone any use of $(call cc-option..) until we have
included the arch specific Makefile so we try with the correct $(CC)
version."
