From the make(1) manpage:
.MAIN If no target is specified when make is invoked, this target
will be built. This is always set, either explicitly, or
implicitly when make selects the default target, to give the
user a way to refer to the default target on the command
line.
The bsd.port.mk does define a .MAIN target so that is the target that
gets used when no target is specified.
