Unless the build system needs to install these .dwo files someplace
where gdb can find them, no?

I believe that will be the common theme: first it would seem the
build system doesn't need to care about some outputs (debug info,
SARIF files) but after a moment of reflection one realizes that
there are use-cases where the build system would need to be
involved.
