Robert opened a bug for a broken link in the doc, see

This is a valid bug, a regression in 

e1bcfe4d8 dev-manual: remove unused labels

Unfortunately, it opens a can of worms... since it looks like the built in linkcheck did not detect the broken links, and this is not the only broken link. 

I ran an online link checker on https://docs.yoctoproject.org/dev-manual/common-tasks.html, and it reported the following errors with anchors.. they look like they are regression with the commit above..

Anyone have any recommendations on how to configure the builtin linkcheck so that it reports such errors?
