Subject: [PATCH] Prevent the NEON check in configure from passing under
aarch64.
The test verifies that the NEON C intrinsics work, but the rest of the
codebase uses lots of direct ARMv7 NEON assembly. The same intrinsics
work in A64, but the assembly is slightly different.
Prevent the check from passing so that we don't use this where it won't
work.
