I had the same confusion when I had a (brief) look into my
own autobuilder failure and made a feeble attempt at
tracking it down.  Maybe a bug in automake-1.16...

Nick: Incidentally, that's not the preferred way to set the
default values; that's in ld/configure.tgt.  As I mentioned
in the bugzilla, see my commit 5d02a15c69c6.  OTOH, if I'm
wrong and miss something, it'd be nice to know, for future
reference.
