It causes build failures with unusual CC/HOSTCC combinations.

  HOSTCC  scripts/mod/modpost.o - due to target missing
In file included from include/linux/string.h:5,
                 from scripts/mod/../../include/linux/license.h:5,

...

The problem is that HOSTCC is not necessarily the same compiler or even
architecture as CC and pulling in <linux/compiler.h> or <asm/rwonce.h>
files indirectly isn't a good idea then.

My toolchain is providing HOSTCC = gcc (MacPorts) and CC = arm-linux-gnueabihf
(built from gcc source) and all running on Darwin.

If I change the include to <string.h> I can then "HOSTCC scripts/mod/modpost.c"
but then it fails for "CC kernel/module/main.c" not finding <string.h>:

  CC      kernel/module/main.o - due to target missing
In file included from kernel/module/main.c:43:0:
./include/linux/license.h:5:20: fatal error: string.h: No such file or directory
 #include <string.h>
                    ^
compilation terminated.
