NetBSD  8.99.21 NetBSD 8.99.21 (GENERIC32_IP12) #1: Sun Aug 12 14:48:19 UTC 2018  naruaki@xserve:/usr/obj.sgimips/sys/arch/sgimips/compile/GENERIC32_IP2x sgimips

>Description:
Old Sgi machine (Indigo or Indy) don't understand ELF, so we may need an ECOFF binary.
However, "objcopy -O ecoff-bigmips" is broken.
As a result, aoutboot is broken.
