    arm: ignore inapplicable .arch=no...
    
    Unlike for command line options, where a base architecture needs to be
    provided explicitly, the .arch directive doesn't have such a
    requirement. Therefore it is odd that disabling of an inapplicable
    extension isn't silently ignored; claiming "not allowed for the current
    base architecture" is at best misleading. Alter the error path to emit a
    more "soft" diagnostic in that case instead.
