Makefile: Include subdirectories in "make cover" reports
We generate profiling files in all the $(OBJECTS) dirs. Aggregate results from there, and add them to the corresponding clean target. Also expand the gcov arguments. Generate reports for things like "x() || y()" using --all-blocks, and add --preserve-paths since we're profiling in subdirectories now.
