The build failed. Needed to do =apt-get build-dep glibc=. This wanted =makeinfo=, but still failed, unable to find =selinux/selinux.h= a long way into the build. Since =/usr/include/selinux/selinux.h= existed, I tried
-=apt-get install linux-headers-4.9.0-3-all=.
+=apt-get install linux-headers-4.9.0-3-all=. This didn't help. I tried starting over, in case the selinux headers were supposed to have been copied into the tree; didn't help. Looked at other glibc external build comments, tried =apt-get install gcc-multilib=, because of the =debian/include= silliness. (Why bother if you're going to make symlinks?)
Run =apt-get install texi2html= to get makeinfo.
