You think of anything better than placing each variable in its own
section and placing them manually in the linker script in the order I
like? I would like to avoid any messing with linker script if that's
possible... If there's nothing better I may end up using suffixes
("section.1", "section.2", "section.3", ...) and sort the sections in
the linker script (`*(SORT(.section.*));`), but I would still prefer to
solve that in the source file only.

No worries, it won't optimize them away, there's also a header where
these variables are declared with `extern ...` (omitted that in the
example, as this doesn't change anything) and all of them will be used
in the project. I'm just concerned about their order.
