_We_ don't use liblzma for anything though, so this is kind of
superfluous. As I understood you, just installing liblzma-dev makes
the build successful, right? Making this change just lead to better
error messages when it's not installed?

What is the distro you're using? The ones we build-test on in gitlab
CI (Fedora, Debian) both have libdw's development package depend on
liblzma.
