This (now in linux-next) causes m68k/allmodconfig to fail for me:
CHK include/linux/version.h
CHK include/generated/utsrelease.h
CC kernel/bounds.s
cc1: error: unrecognized command line option "-fno-ipa-cp-clone"
Somehow, "$(call cc-option,-fno-ipa-cp-clone,)" doesn't detect that my
toolchain (gcc version 4.1.2 20061115 (prerelease) (Ubuntu 4.1.1-21))
doesn't support this option.
I tried playing with the trailing comma (why do the first 2 tests have it,
and the 3rd one doesn't?), but that didn't make a difference.
linux-next builds (using a newer toolchain) don't show this.
