This, in and of itself, is OK.  It however exposes a problem on x86,
that is also potentially found on most other arches.  Namely that
arch/{arm,m68k,mips,nds32,x86}/include/asm/global_data.h reference
CONFIG_foo but do not have an #include of config.h directly.  On other
platforms that compiled this file, something else drags in config.h and
it's OK, but on x86 it's a fatal error.
