[PATCH 1/2] Sync from upstream gnulib and autoconf.

[Paul Eggert]

In trying to install a simple pitch to Bison I found that
it didn't bootstrap at all, due to changes to Gnulib in
the past few months.  What a hassle.  This turned a 15-minute
fix into something that took hours to check.  Anyway, here's
part one of the fix.  (I can't ship the fix as a single patch,
as I couldn't find any single patch for which "bootstrap"
would work.)
