Is there any particular motivation (to do this now), given it doesn't work/can't be tested?

Not sure about this issue, or making this change. Looks like it needs more investigation. See my comment here: https://github.com/bitcoin/bitcoin/issues/30978#issuecomment-2388086723.

@dergoegge you likely also have some thoughts here?

Also in `test_deterministic_coverage.sh`: `Run \"./configure --enable-lcov\"`

Also needs a release note.

Is this still an issue given recent CMake changes?
