Since __kernel_long_t (time_t) is long long, we need to tell the rest of
kernel that we use 64bit time_t for compat when the task is not an
AARCH32 task.  The reason why we check AARCH32 rather than ILP32 here is
because if we don't have AARCH32 compiled in (which is going to be the common case due to AARCH32 requiring 4k pages).
