evbppc and alpha build breakage, but not in releng autobuild

[Taylor R Campbell <campbell+netbsd-current-users%mumble.net@localhost>]

I tried to build evbppc and alpha releases today, with CVS as of
yesterday (plus some local changes that should matter only for x86 and
arm) on NetBSD/amd64 6.0_STABLE as of January (with a 6.99.16 kernel),
using

   build.sh -O ../obj.$arch -U -u -m $arch -j12 tools
   build.sh -O ../obj.$arch -U -u -m $arch -j12 release

and they both failed.  Curiously, the releng autobuilds have been
succeeding, and the code the build choked on hasn't changed recently.
Any idea why the releng autobuilds don't reflect these failures?
