Fix compiler error when using ./configure --enable-dev-mode --enable-coverage 

When DONT_OPTIMIZE is enabled with dev-mode, it causes a shadow compilation
to be done with output to /dev/null.  This can cause errors with coverage
when GCC attempts to write to /dev/null.gcno.  This change disables
coverage for the shadow compilation.
