#3756: Missing -lz option in testsuite
----------------------------------+-----------------------------------------

        Type:  bug                |      Status:  new       
    Priority:  normal             |   Component:  Test Suite
     Version:  6.12.1             |    Keywords:            
          Os:  Unknown/Multiple   |    Testcase:            
Architecture:  Unknown/Multiple   |     Failure:  Other     
----------------------------------+-----------------------------------------
 Running the testsuite with a newly built 6.12.1, I got
 {{{
 OVERALL SUMMARY for test run started at Mo 14. Dez 18:06:00 CET 2009
     2352 total tests, which gave rise to
    13034 test cases, of which
        0 caused framework failures
     2760 were skipped

     9471 expected passes
      328 expected failures
        0 unexpected passes
      475 unexpected failures
 }}}
 All but 8 (unless I miscounted) of the unexpected failures were in way
 threaded1, the overwhelming majority due to
 {{{
 /usr/src/packages/BUILD/binutils-2.19/build-
 dir/bfd/../../bfd/compress.c:96:0:
      undefined reference to `inflateInit_'

 dir/bfd/../../bfd/compress.c:103:0:

 *** 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
 {{{

        0 unexpected passes
        3 unexpected failures

 Unexpected failures:

 }}}
 which seems to confirm the suspicion.
