    [arm] Simplify run-time CPU selection. · 76ea8f2f
    jacob.bramley authored
    This replaces the target-selection options (such as "--enable-vfp3")
    with a simpler, absolute "--arm-arch" option. This eliminates inferences
    and avoids surprising behaviour in impossible situations (such as
    "--enable-vfp3 --no-enable-armv7").
    
    The available options are:
        --arm-arch=armv6          ARMv6 + VFPv2
        --arm-arch=armv7          ARMv7 + VFPv3-D32 + NEON
        --arm-arch=armv7+sudiv    ARMv7 + VFPv4-D32 + NEON + SUDIV
        --arm-arch=armv8          ARMv8 (+ all of the above)
    
    For now, the default setting is "armv8", which results in behaviour very
    similar to the existing defaults.
