[BUG] Build error for 4.15-rc3 kernel caused by patch "kbuild: Add a cache for generated variables"

I just upgraded gcc to 6.4 on my centos 7 machine by Arnd's suggestion.
But, I ran into the below compile error with 4.15-rc3 kernel:
In file included from ./include/uapi/linux/uuid.h:21:0,
./include/linux/string.h:8:20: fatal error: stdarg.h: No such file or
I bisected to commit 3298b690b21cdbe6b2ae8076d9147027f396f2b1 ("kbuild:
Add a cache for generated variables"). Once I revert this commit, kernel
build is fine.
gcc 4.8.5 is fine to build kernel with this commit.
I'm not quite sure if this is a bug or my gcc install is skewed although
it can build kernel without that commit since that commit might
exacerbate the case.
Any hint is appreciated
