+Subject: [PATCH] Fix failing aarch64 (ARM64) build
+
+ARM64 systems do not use ARM Exception Handling ABI (EHABI), but rather the DWARF exception handling standard.
+The fix turns off special ARM handling of exceptions when the target platform is ARM64.
+This enables builds of the codebase on ARM64 systems with standard implementation of libunwind as shipped with gcc 5+.
