    include/prereq-build: fix ldconfig-stub symlink on macos and BSD OSs
    
    Some OS may have the true bin to a different location than /bin/true.
    BSD based system and macos have true on /usr/bin/true.
    
    Fix this by checking both location and take the one available in the
    system.
