Nope, it's a straight in-tree build. I made it work after a few more
failed tries with a call like

GENHTML_FLAGS="-q --legend --ignore-errors unmapped,corrupt,inconsistent,range"
LCOVFLAGS="-q --legend --ignore-errors usage"
make coverage-html

... and we have a nice (??) trace of what errors are being ignored. I
think this is absolutely bonkers, but who knows when or if lcov and its
tools are going to be fixed in a way that allows our tree to be
processed correctly.

However, it appears that there are problems with the CSS, because the
lines are not colored anymore. I have no idea how to get this to work,
but you can see the result running lcov 2.0 in
