Ancient gcc doesn't know about __builtin_unreachable(), causing
lots of instances of a harmless warning:
include/xen/arm/page.h: In function 'arbitrary_virt_to_machine':
include/xen/arm/page.h:85: warning: no return statement in function returning non-void
Adding a return statement doesn't change the behavior here, but
shuts up that warning.
