binturong seemed to be clean on HEAD for a while now, and the failures
~80 days ago seem to have had different symptoms (the src/bin move):
http://buildfarm.postgresql.org/cgi-bin/show_history.pl?nm=binturong&br=HEAD

other branches are less nice looking for various reasons, but there's
another recurring error:
FATAL: could not open relation mapping file "global/pg_filenode.map": No such file or directory

Those seem to indicate something going seriously wrong to me.
