those should all be perfectly acceptable failures.

but this one is very uncommon. I can't even find a way to turn off
CONFIG_KALLSYMS, except by editing .config. Perhaps you have
turned on CONFIG_EMBEDDED ? - if so, you need a lot of kernel
knowledge to get a good build.

I haven't tried a build without modules on a recent version of
LFS, but building without modules should be perfectly acceptable.
