When using llvm we need to set the gcov-tool to "llvm-cov gcov" but
the lcov tool is incapable of passing arguments to the gcov-tool. i.e.
the following cannot work:
$ lcov --gcov-tool "llvm-cov gcov" ...
Instead, create a symlink to llvm-cov prefixed as `gcov` which by the
documentation of llvm-cov will alias to `llvm-cov gcov` subcommand.

Fix build step to enable CONFIG_COVERAGE_DUMP, otherwise
we won't get coverage data dump required for next step.
