fix building coreboot images on i686 hosts
firstly, memtest86+ is currently not cross compiled and relies on 64-bit headers (x86_64 only). a 32-bit distro is unlikely to be able to build 64-bit binaries. secondly: vboot throws a build error due to -Werror when building on 32-bit hosts. we rely on vboot code to build cbfstool, so turn off -Werror on vboot that's all. 32-bit hosts are not recommended; it is assumed that you are building on an x86_64 host. work will go into the build system at a later date to make it more portable, by cross compiling everything, but this should fix 32-bit for now. there are some x60/t60 users who still want to build roms, so let's allow them that possibility.
