    hostapd: avoid unnecessary package rebuilds
    
    Package hostapd-common is a dependency of every other package defined in
    hostpad Makefile.  It is currently built next to the bottom of that
    Makefile's package list.
    
    If you run make back to back, then check-compile will compare the
    hostapd-common timestamp to the variant being compiled, to decide if the
    varint needs to be rebuilt or not.  Since the hostapd-conf package is
    built towards the end of the list, it will be newer than most of the
    variants, causing unnecessary package rebuilds.
    
    Move it to the top, so that its timestamp will be older than dependent
    packages, avoiding unnecessary rebuild of every selected variant.
