    build:wafsamba: Ensure that check_group_ordering can be overridden
    
    Group ordering verifications are performed by default in Waf 1.8,
    so this method will be redundant. The purpose of this change is
    to make it easier to disable check_group_ordering as it contains
    code that is very specific to Waf 1.5.
