Right now, the recipe for building chromium84 is settings the GN variable symbol_level to 0. This implies all web runtime is built with -g0 even in debugging packages. We know default Yocto level (and default Chromium level for official builds) is -g2 and that can be problematic as the size of the debugging symbols is several gigabytes.

But, by default, we can set symbol_level to 1, so we can at least have stack traces. This should not mean the size of the debugging packages to be very big (it is in the order of 100MB) and still should be useful for development purposes.
