Yeah, that's fine. We do those crazy include paths in other tools too:

$ grep -ErIn '(\.\.\/){2,}' tools/
tools/usb/ffs-test.c:42:#include "../../include/uapi/linux/usb/functionfs.h"
tools/perf/bench/mem-memset-x86-64-asm.S:4:#include "../../../arch/x86/lib/memset_64.S"
tools/perf/bench/mem-memcpy-x86-64-asm.S:4:#include "../../../arch/x86/lib/memcpy_64.S"
tools/perf/util/include/asm/byteorder.h:2:#include "../../../../include/uapi/linux/swab.h"
tools/perf/util/include/linux/const.h:1:#include "../../../../include/uapi/linux/const.h"
...

Add

typedef unsigned short u16;

before the include maybe?
