autoreconf no longer works outside the current directory

[Olly Betts]

autoreconf is documented to work outside the current directory, and used
to in autoconf 2.59.  The patch below fixes that.

To reproduce, pick any autoconf-ed project, change to the directory
above and run "autoreconf PROJECTDIRECTORY".

I also notice a worrying mismatch between the comment and the code just
above the patched location:

  # Autoreconf all the given configure.ac.  A while loop, not a for,
  # since the list can change at runtime because of AC_CONFIG_SUBDIRS.
  for my $directory (@ARGV)
    
Cheers,
    Olly
