    Remove dead code in the cscope target
    
    arm64 is the only currently supported architecture that has
    ${MACHINE_CPUARCH} set to a different value (aarch64) than ${MACHINE}
    (arm64), as described in arch(7). However, there is no source directory
    associated with arm64 that has a name set to ${MACHINE_CPUARCH}.
    
    Remove the dead code that adds a directory with a name set to
    ${MACHINE_CPUARCH} to a list of directories indexed with cscope.
    This change allows to use the cscope target on arm64.
