Missing -lz option in testsuite

Running the testsuite with a newly built 6.12.1, I got

All but 8 (unless I miscounted) of the unexpected failures were in way threaded1, the overwhelming majority due to

*** unexpected failure for fileStatus(threaded1)

That looks like a missing -lz option in the testsuite. Adding "EXTRA_HC_OPTS += -optl-lz" to test.mk and running "make stage=2 WAY=threaded1" produced

       3 unexpected failures

Unexpected failures:
   2317(threaded1)
   galois_raytrace(threaded1)
   qq005(threaded1)

which seems to confirm the suspicion.
