Encountered two issues, documentation related.
1. Anything where doxygen calls dot (graphviz), it just hangs,
forever, no message. Looked at rebuilding graphviz and doxygen, tried
a few things, no simple fix. It seems to be a known issue with other
packages, applying this quick fix: Just toggle off any HAVE_DOT from
Doxygen file.
If you look at my 2024-07 [ITP] cmocka, I found:

Yeah, this shows up when building the libxcb documentation with doxygen
as well.
When I investigated, it seems like the dot processes have all finished,
but doxygen is still waiting for them (so a signal gone missing maybe?).
This seems to be a regression which slipped in between 3.3.6 and 3.4.0,
but I haven't bisected it further than that.
