the normal case when BUILDLINK_DEPENDS.<pkg> isn't specified, it receives a value only once due to the multiple inclusion protection in the bulldlink3.mk files. In the case where a package includes several buildlink3.mk files that each want a slightly different version of another dependency, having BUILDLINK_DEPENDS.<pkg> be a list allows for the strictest <pkg> dependency to be matched.
