No, it's not the only way *I* know how to, but if you aren't
going to follow UPDATING, then *you* are expected to figure
it out :-)

Your problem is that you don't have an up-to-date kernel src
(src/sys) directory with includes in your build environment.
Your libc is being built against an old set of includes, so
it is up to you how to want to modify your build environment
to account for this.
