I haven't done cross-compilation really myself. I have only used the
"Additions and Overrides" page for setting a define for the project +
all dependent packages. It worked well for that.
Indeed this page is intimidating and maybe could be improved. I don't
know exactly how.

Still I think you confused "Build modes" with "Additions and
Overrides". They are very different things. A build mode contains all
compiler options, including the "Additions and Overrides" part.
