I got a response back from the FSF (gnu.org #773481):

Hi Pedro,

1) It is certainly the case that you should add a copyright line for the
FSF when nontrivial changes are made.  This is what reflects reality,
and it has always been the stated practice to follow, though I gather
libc did not bother to do so.  It is explicitly discussed at the end of
the Copyright Notices section you cited,
http://www.gnu.org/prep/maintain/maintain.html#Copyright-Notices.
