Perhaps it's hard to read, but we haven't introduced new conditionality.

Previously we'd only build the tests directory if CONFIG_DWARF_UNWIND
was selected, so tests/dwarf-unwind.o was always dependent on that.

Now we always try to build the tests directory, and move the
CONFIG_DWARF_UNWIND guard specifically to tests/dwarf-unwind.o.

Thanks,
Mark.
