kbuild: avoid conflict between -ffunction-sections and -pg on gcc-4.7
Arnd Bergmann reported: "When ftrace is enabled and we build with gcc-4.7 or older, we get a warning for each file on architectures that select CONFIG_LD_DEAD_CODE_DATA_ELIMINATION: warning: -ffunction-sections disabled; it makes profiling impossible [enabled by default] " Since commit c3f0d0bc5b01 ("kbuild, LLVMLinux: Add -Werror to cc-option to support clang"), warnings are treated as errors in cc-option checks. CC_FLAGS_FTRACE is blindly added to KBUILD_CFLAGS, so $(call cc-option,-ffunction-sections,) should be moved below it in order to detect the conflict between the two options.
