Could we just pass these object files around as test resources instead? Not that xxd was not present in most systems, but looks like extra work and complexity.

The problem is that it is hard to determine file location paths when functional test is run.
The test needs to not reference the build directory structure. And installing objects somewhere in build
requires more steps in meson. This was the easiest way which is what the cfgfiles test was already doing.
