Add optional usage of gcov for test coverage
Use gcov to find how much code coverage our current testing gets. This
can be enabled by passing --with-gcov to configure and running "make
gcov". This is limited to gcc. Here's a run from the current code (for
some reason, gcov insists on profiling gstring.h).
