There are compiler issues when building with -mcpu=native with popular
compilers, such as GCC-8.4 and clang (which doesn't define
__ARM_FEATURE_ATOMIC). Fix this by always specifying the proper machine
args and never using the native flags.
Fixes: 78ac8eac7e8a ("config/arm: use native machine build arguments")
