Regenerate the files using automake-1.15 & autoconf-2.69 to match the
binutils/gdb/gcc projects.  Ran:

libgloss $ find -name configure.ac -printf '%h\n' | while read d; do
  (cd $d; export WANT_AUTOCONF=2.69 WANT_AUTOMAKE=1.15;
   aclocal-1.15 -I.. && autoconf-2.69); done

I'm attaching the patch compressed because it's much too large for the
mailing list otherwise.
