I've applied, even though I'm not super happy with the fact that we
already had a (useless?) BR2_PACKAGE_HOST_LINUX_HEADERS option, and we
now have both a Config.in.host and a Config.in file for what is really
a target package...

Ideally, we would move all the options to the Config.in file, and
rename them.. but that would cause so much Config.in.legacy trouble :-/

Thanks,

Thomas
