These tests rely on an unintended behavior that when the driver performs both compilation and linking phases, the .gcno & .gcda files are placed in PWD. The behavior will be fixed to respect -o (match -ftime-trace, -gsplit-dwarf, and GCC). Add -dumpdir ./ so that the tests will work with or without the behavior change, and make it easy to compare the coverage behavior with GCC.
