arm: Always unconditionally declare .arch armv7-a

We already unconditionally declare .fpu neon and try to build all the
neon codepaths (but only execute them conditionally based on a runtime
check).

This fixes builds targeting armv6, where the rbit instruction isn't
available. This instruction is only used within a neon function in
any case, so there's little point in emulating it.
