From b56846a43019355a3d302c1c2a03e40a1d61a737 Mon Sep 17 00:00:00 2001

Subject: configure: remove support for obsolete platforms

- #error hack for MIPSpro compiler from unix/clock-*
- irix exclusions from unix/*iconv
- hpux defines from unix/{getifaddrs,ipv6ifname} (the obsolete
  hpuxi-g++-64 spec would add them automatically anyway)
