Why must ld do that? You have
_sidata = .;
. = ALIGN(4);
.data may be at a different address due to alignment of .data, or ld
may have inserted an orphan section between the assignment and .data.
Probably your best option is to use
_sidata = ADDR (.data);
Put this somewhere after the .data section.
