Subject: [PATCH] Fix the AArch64 small object class lookup.

This was generating a relocation that didn't do the right thing and
didn't raise linker errors.  Now it is using GOT-relative addressing.

In combination with the last two commits, this now makes all of the
objc_msgSend tests pass on AArch64.

Fixes #105
