[coreboot] autoconf warning while make crossgcc on debian 6.0.5 and 7.2.0

[Gelip]

Hi. I tray use two debian version for coreboot project. While make crossgcc have some warnings in crossgcc-build.log (binutils):

debian 6.0.5 binutils crossgcc-build.log:
-------------------------------------------------------------------------
configure.ac:33: error: Please use exactly Autoconf 2.64 instead of 2.67.
config/override.m4:12: _GCC_AUTOCONF_VERSION_CHECK is expanded from...
configure.ac:33: the top level
autom4te: /usr/bin/m4 failed with exit status: 1
-------------------------------------------------------------------------

debian 7.2.0 binutils crossgcc-build.log:
-------------------------------------------------------------------------
./buildgcc: line 453: autoconf: command not found
-------------------------------------------------------------------------

but in both operating systems build ends success. Commands make menuconfig and make working OK and build coreboot.rom
Does this have any impact on the project coreboot? Can this just to ignore?
