    Makefile-workaround for OpenBSD
    
    Thanks Hiltjo for reporting this!
    
    For some reason, OpenBSD make does not add $(BIN).o to the dependency list
    when it sees the $(BIN) target rule. It does so however when it does the
    conversion from .c to .o.
    This behaviour is unique for OpenBSD make as far as I've seen, and for
    the time being, this workaround will manually add the object to the
    dependency list.
    This is not POSIX compliant and in GNU make it just evaluates to an
    empty string, but it works until this has been investigated further.
