[Xcb] Are the util-common-m4 submodules relative on purpose?

If you want  to publish your own copy of util*  somewhere else, then you
will have  to modify .gitsubmodules (and  perform a commit  for that) to
match the location of your repositories AFAIK.

And SSH?

As I said before, it was done on purpose (e.g. I explicitely specified a
relative URL to "git submodule add").
