-r319991 buildkernel waiting in sed for terminal input (the buildworld part completes first), amd64->powerpc cross build

[Mark Millard]

I've been having amd64 -> powerpc cross builds that
stop with sed waiting for terminal input:

  780  0  Is   0:00.00 -sh (sh)
  786  0  I    0:00.01 - su
  787  0  I    0:00.01 `-- su (sh)
  792  0  I+   0:00.00   `-- /bin/sh /root/sys_build_scripts.amd64-host/make_powerpcvtsc_nodebug_clang_bootstrap-amd64-host.sh -j16 buildworld buildkernel
  795  0  S+   0:06.95     `-- script /root/sys_typescripts/typescript_make_powerpcvtsc_nodebug_clang_bootstrap-amd64-host-2017-06-15:17:17:51 env __MAKE_CONF=/root/src.configs/make.conf SRCCONF=/dev
  796  1  Is+  0:07.34       `-- make -j16 buildworld buildkernel
24978  1  I+   0:00.00         `-- sed -n /^CMD/s,^CMD ,,p


This is for a build that currently fails with:

--- all_subdir_sys ---
Building /usr/obj/powerpcvtsc_clang/powerpc.powerpc/usr/src/sys/boot/powerpc/boot1.chrp/boot1.elf
--- boot1.elf ---

.ERROR_META_FILE='/usr/obj/powerpcvtsc_clang/powerpc.powerpc/usr/src/sys/boot/powerpc/boot1.chrp/boot1.elf.meta'
. . .

and its later consequences.

Since it is already a failed build I just ^C out.
