Move cc-option to below arch-specific setup

d0115552 · Linus Torvalds <[email protected]> · 2009-03-19 15:53:19 -07:00

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."
