I'm a bit confused about debian build errors:

    ERROR: The certificate of 'xenbits.xen.org' is not trusted.
    ERROR: The certificate of 'xenbits.xen.org' has expired.

Is clock on gitlab runners (way) off?

First of all, such change definitely wants a separate patch,
de-supporting some configurations do not belong to "Replace git:// and
http:// with https://" patch. But then, I don't think that's correct
approach. It is a bug to be fixes, instead of breaking it even more.
configure script already supports Xen's mirror, and I think it's even
enabled by default (see --enable-extfiles), and also supports providing
alternative download location (via env variables). So it seems your
change here in fact breaks something that was working before...
