    arm: fix build with gcc 7
    
    The compiler dislikes duplicate "const", and the ones it complains
    about look like they we in fact meant to be placed differently.
    
    Also fix array_access_okay() (just like on x86), despite the construct
    being unused on ARM: -Wint-in-bool-context, enabled by default in
    gcc 7, doesn't like multiplication in conditional operators. "Hide" it,
    at the risk of the next compiler version becoming smarter and
    recognizing even that. (The hope is that added smartness then would
    also better deal with legitimate cases like the one here.) The change
    could have been done in access_ok(), but I think we better keep it at
    the place the compiler is actually unhappy about.
