It's not preinstalled, but it's available as a package in all distribs
that contain X.org (even non-Linux distrib).
If we add the upstream URL for all packages that are not available by
default, we need one for libxml-devel and numactl-devel too since devel
headers are rarely installed by default.
In brief, just remove that URL :)

This text is way too long. That section about dependencies was meant to
be easy to read before a first manual build of hwloc, that's why it's
a small list of short items. You're adding half a page about libpci in the
middle, making it hard to read. That long discussion can move somewhere
else, I'd say a FAQ entry at the end of doxy.

You really need to stop thinking that libpciaccess needs to be installed manually
