Fix a couple of tests that were incorrectly using configuration.dwarf_version

[jimingham]

The tests were using the variable directly to get the dwarf version used for the test. That's only the overridden value, and won't be set if we're using the compiler default. I also put a comment by the variable to make sure people don't make the same mistake in the future.
