I can see that libsodium had the same build break problem with autoconf-2.69 and the compatibility patch for 2.63 was reverted. This is the problem here as well. We could revert this change and verify if crosscompilation still works. https://github.com/jedisct1/libsodium/pull/216
In UrJTAG I got rid of this problem by removing following lines from acinclude.m4: 152 dnl AS_VAR_APPEND 153 dnl ------------- 154 dnl 155 dnl this was added in autoconf-2.64+ 156 dnl 157 m4_ifndef([AS_VAR_APPEND],[dnl 158 AC_DEFUN([AS_VAR_APPEND], [$1=$$1$2]) 159 ])dnl iCeDeROM:urjtag cederom$ autoconf --version autoconf (GNU Autoconf) 2.69 Copyright (C) 2012 Free Software Foundation, Inc.
