[PATCH v4 0/2] ci: detect more warnings via `-Og`

Hi,

this is the fourth version of my patch series that starts to compile with `-Og` in one of our CI jobs. This is done to surface more warnings from the compiler that might not show with other optimization levels.

Changes compared to v3:

  - Remove the first patch as Junio has moved it into a separate
    topic so that it can be fast-tracked.

  - Drop the patch that changes CI jobs to compile with V=1.

  - Drop the `override` statement and instead implement CFLAGS_APPEND
    and LDFLAGS_APPEND via ALL_CFLAGS and ALL_LDFLAGS, respectively, as
    suggested by Peff.

The range diff is not all that useful for this version, and the patch series is tiny, so I dropped it.

Thanks!

Patrick
