Rationale (May, 2015):

The material in 6.6 [basic.link] deals with linkage concepts, while 9.2.2 [dcl.stc] is concerned with the syntactic constructs in a program that result in the linkages described in 6.6 [basic.link]. CWG felt that the referenced paragraph falls more into the latter category than the former.

9.2.2 [dcl.stc] paragraph 7 seems out of place in the current organization of the Standard:

The linkages implied by successive declarations for a given entity shall agree. That is, within a given scope, each declaration declaring the same variable name or the same overloading of a function name shall imply the same linkage. Each function in a given set of overloaded functions can have a different linkage, however. [Example:...

The preceding two paragraphs on static and extern simply defer to 6.6 [basic.link] to describe their interaction with linkage, so it seems appropriate for this paragraph to move there as well so that all the information on linkage is in one place.
