A previous patch ([1]) introduced a build regression on aarch64-none-elf
target. The changes were primarilly tested on aarch64-unknown-linux-gnu,
so the issue was missed during development.
The includes are slighly different between the two targets, and due to some
include rules ([2]), "aarch64-unwind-def.h" was not found.
