[Libunwind-devel] [RFC PATCH 1/2] aarch64: introduce build support for aarch64_be target

[Victor Kamensky]

Introduce support for aarch64_be, aarch64 big endian, target.
We would like to reuse all code that was done for aarch64
(little endian) target. So we reset libunwind arch from
aarch64_be to aarch64 in case of target_arch=aarch64_be.
