You can do the same with MULTI as well to achieve 0 or many. This has
been documented in the handbook now.
Another common question is how to check if an option is not set. We all
try !${PORT_OPTIONS:MFOO} to find it does not work.
Use empty():
.if empty(PORT_OPTIONS:MFOO)
CONFIGURE_ARGS+= --disable-foo
.else
CONFIGURE_ARGS+= --enable-foo
.endif
Wiki is updated on this, handbook being updated.
