From: Pekka Enberg <penberg@xxxxxxxxxx>
Sparse treats code as 32-bit which causes problems for userspace projects on
x86-64 Fedora if you don't have the 32-bit glibc compat package installed
("glib-devel.i686"):
$ ./sparse allocate.c
/usr/include/gnu/stubs.h:7:12: error: unable to open 'gnu/stubs-32.h'
Fix the issue by defining relevant macros on 64-bit.
