So let's add a short explanation to clarify the difference.

Generally we have these so we can use kernel structs +# and defines that are more recent than the headers that might be +# installed on the host system. Usually this script can do simple +# file copies for these headers. +# +# - include/standard-headers/ for files that are used for guest +# device emulation and are required on all hosts. For instance, we +# get our definitions of the virtio structures from the Linux +# kernel headers, but we need those definitions regardless of which +# host OS we are building for. This script has to be careful to +# sanitize the headers to remove any use of Linux-specifics such as +# types like "__u64".
