It is the fault of autoconf 2.72, actually. Try the patch below.

*** All internal uses of AC_EGREP_CPP and AC_EGREP_HEADER have been removed.
   These macros look for text matching a regular expression in the
   output of the C preprocessor.  Their use has been discouraged for
   many years, as they tend to be unreliable; it is better to find a
   way to use AC_COMPILE_IFELSE or AC_PREPROC_IFELSE instead.  We have
   finally taken our own advice.

   This change might break configure scripts that expected probes for
   ‘grep’ and/or the C preprocessor to happen as a side effect of an
   unrelated operation.  Such scripts can be fixed by adding
   AC_PROG_EGREP and/or AC_PROG_CPP in an appropriate place.

   The macros affected by this change are AC_C_STRINGIZE,
   AC_C_VARARRAYS, AC_FUNC_GETGROUPS, AC_FUNC_GETLOADAVG,
   AC_HEADER_TIOCGWINSZ, AC_PROG_GCC_TRADITIONAL, AC_TYPE_GETGROUPS,
   AC_TYPE_UID_T, and AC_XENIX_DIR. Many of these macros are themselves
   obsolete; if your configure script uses any of them, check whether
   it is actually needed.
