This is an internal kernel header.

This only contains the kernel headers exposed to userspace, i.e the
UAPI (user-space API). There is absolutely no reason for list.h to be
in there.

You need to give more details about the Barebox failure you're seeing:
which version you're trying to build, what is the build error. But the
error is clearly not due to <linux/list.h> being missing from the
compiler sysroot.
