Mike Frysinger a100e80fc9 require autoconf-2.69 exactly
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.
