Add lame aarch64 userspace support.

We don't (can't) have runtime L1 cache size detection on aarch64 without
help.  Of course, line size is always 64 bytes (and that can be found at
runtime); but the total L1 dcache size is not discoverable unless the
kernel (or something else at EL0) has flipped the ECT bit in the system
control register.  This could well be why getconf LEVEL1_DCACHE_SIZE
fails.  In any case, I can't see how it would work.

So, abuse the fact that no aarch64 impl has L1 dcache < 32KB and be happy.
