Move creation of last section id from ld linker script LONG() usage to C code with last section attribute. The use of `LONG()` works correctly with ld but lld emits a warning because .last_section section is not allocated as there are no matching input sections and discards the `LONG()` call, meaning the last section identifier will not be present in the flash. > ld.lld: warning: ignoring memory region assignment for > non-allocatable section '.last_section' Placing the last section id in `.last_section` in C code makes lld allocate the memory for the id and thereby create the output section with the correct output.
