The newlib & libgloss dirs are already generated using autoconf-2.69. To avoid merging new code and/or accidental regeneration using diff versions, leverage config/override.m4 to pin to 2.69 exactly. This matches what gcc/binutils/gdb are already doing. The README file already says to use autoconf-2.69. To accomplish this, it's just as simple as adding -I flags to the top-level config/ dir when running aclocal. This is because the override.m4 file overrides AC_INIT to first require the specific autoconf version before calling the real AC_INIT.
