I still had the window open that had the build failure:

  LD      sound/pci/snd-es1968.o
  CC      fs/btrfs/zlib.o
drivers/net/cnic.c: In function ‘init_bnx2_cnic’:
drivers/net/cnic.c:2524: error: implicit declaration of function 
‘__symbol_get’
drivers/net/cnic.c:2524: warning: assignment makes pointer from 
integer without a cast
distcc[22461] ERROR: compile drivers/net/cnic.c on ph/32 failed
make[2]: *** [drivers/net/cnic.o] Error 1
make[2]: *** Waiting for unfinished jobs....
  CC      drivers/ide/trm290.o
  CC      drivers/scsi/cxgb3i/cxgb3i_ddp.o
  LD      sound/pci/snd-fm801.o
  CC      net/sched/sch_drr.o
  CC      fs/cifs/xattr.o
  CC      drivers/scsi/mpt2sas/mpt2sas_base.o

So it's real - even if the fix is bogus. But it's a different config 
- i'll now try to figure out which one it is and why the build fails 
...
