For which target did you build? I actually don't see it for a small
number, ie:
  * xtensa-linux
  * fr30-elf
  * hppa2.0-hpux11.9
  * hppa64-hpux
  * hppa64-hpux11.0
  * hppa64-hpux11.3
  * ia64-elf
  * ia64-hpux
  * mmix-knuth-mmixware
  * powerpc-darwin7
  * pdp11-aout
  * powerpc-darwin8
  * s390x-ibm-tpf
  * x86_64-apple-darwin

Maybe you had a lucky pick? Only IPv6 connectivity at the moment, but
here are a few (failed) build logs for more common targets:
