build: be robust against install-sh files above the root dir

Explicitly set AC_CONFIG_AUX_DIR.

To reproduce the error avoided by this patch:

  rm install-sh        # in case it was already generated.
  touch ../install-sh  # yes, outside this source tree
  autoreconf -fi

This will produce an error like

  ... error: required file '../' not found installing '../missing'
  src/ installing '../depcomp'
  autoreconf: automake failed with exit status: 1

See also automake (vim `which automake`) and look for 'sub locate_aux_dir'.
