This sounds suspiciously like the .la file(s) is responsible for the
problem. If the .la file mentions libraries that aren't actually
required, and are missing, then builds will fail if they use such .la
files even if they don't actually depend on the missing libraries. You
can grep your other .la files to see if they point to said
libxcb-aux.la, and probably you'll get several hits.
