1) since libzzz.la is referenced as `libzzz.la' in noinst_LTLIBRARIES,
  a) it is built built is the current directory
  b) you should reference it as `libzzz.la' anywhere else in the same 
     Makefile (BSD Make is not able to guess that ./libzzz.la is the 
     same file as libzzz.la, for instance).
So all these $(top_builddir)/libzzz.la really should be libzzz.la.

2) the `LDADD' variable contains the default definition for
all *_LDADD variables.  So linking all you programs against the
same libraries requires only one line (LDADD = $(ZZZ_LIBS) libzzz.la)

When you write 

 zzz_LDADD = $(ZZZ_LIBS) libzzz.la

automake generates 

 zzz_DEPENDENCIES = libzzz.la

automatically.

This is what happens.
