host-lzo is built for the host, so it's quite unlikely that any AVR32
change can have an impact on it.

It sounds like the autoconf host-config.cache has been filled with an
empty value for --target.

Can you show the contents
of /avr/buildroot/output/build/host-config.cache after the failure, and
can you post the *full* build log somewhere ?

Thanks,
