Look's like the check to find Python is now failing for Python 3.8.
The relevant part in configure.ac (line 676 to 688) is this:

AC_ARG_ENABLE([python], [AS_HELP_STRING([--enable-python], [Enable building of Python bindings (default: auto)])],
	[want_python="$enableval"], [want_python=auto])
AS_IF([test "$want_python" != no], [
	PKG_CHECK_MODULES([PYTHON], [$PYTHON_PC], [], [:])
	AS_IF([test -n "$PYTHON_LIBS"], [
		AC_PATH_PROG([SWIG_EXEC], [swig])
		AM_PATH_PYTHON([2.5])
		AS_IF([test -z "$SWIG_EXEC"], [AC_MSG_ERROR([swig is required for Python])])
		AC_DEFINE([ENABLE_PYTHON], [1])
	], [test "$want_python" = yes], [
		AC_MSG_ERROR([python requested but not satisfiable])
	])
])
