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.
