Isn't the better fix to disable coverage for the shadow compilation?

> When coverage and dev-mode are enabled with DONT_OPTIMIZE, it causes build failure.  The double compilation does a 'shadow' build of each file with output to /dev/null.  Unfortunately when coverage is enabled, GCC tries writing to /dev/null.gcno (at least some versions do).  This prevents the build from proceeding.
