| Subject: Move cc-option to below arch-specific setup |
| |
| From: Linus Torvalds <torvalds@linux-foundation.org> |
| |
| 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." |
