Having arm 32/64 bit headers coexisting turns out to be tricky. Unfortunately our wrapper works using wordsize.h and this differs on arm so we can't use it.
Therefore replicate the logic here for arm. I did look into writing our own wordsize.h but we also need to remap kernel headers on arm and since wordsize.h comes from libc, that doesn't work for kernel headers.
