This bug is because an empty .data will be removed by the ld machinery.
I think that bug has been fixed, at least, if you add a
symbol-setting (one without PROVIDE) which seems slightly better
than decorating input .data sections with KEEP, which just stops
--gc-sections for *any* input .data.

"KEEP" is a decoration, not a separate statement. At a minimum,
drop the first "*(.data). It's at least confusing, but might
add a second copy, I'm not sure.
