Mine does:

  --coverage
    This option is used to compile and link code instrumented for
    coverage analysis.  The option is a synonym for -fprofile-arcs
    -ftest-coverage (when compiling) and -lgcov (when linking).  See
    the documentation for those options for more details.

Indeed, I guess the log message is somewhat misleading.
