Update to 1.11.6. From the changelog:

Update to 1.11.5. From the changelog:

- Recovered tcpclient IPv4 connectivity in case of a given IPv4
  address to connect to employing fehQlibs-15 and the enhanced
  dns_ip_qualify routine.

Log message:
Add sysutils to CATEGORIES to match ucspi-tcp.

Log message:
Retire 'djbware-errno-hack' and associated options.mk cleverness.
Instead:

1. Package makefiles including their own options.mk
2. Packages say "SUBST_CLASSES+=djberrno" to get the hack, if needed
3. Packages adjust SUBST_FILES.djberrno, if needed

Should fix bulk build failures due to multiple inclusions of options.mk
and/or incorrect definitions of DJB_ERRNO_HACK.

Approved during the freeze by wiz@.
