PR24786, wrong LMA if first section in overlay is empty
This stops the first overlay section being ignored when empty,
losing its LMA assignment
PR 24786
* ldlang.h (enum section_type): Add first_overlay_section.
* ldlang.c (lang_add_section): Adjust switch statement.
(map_input_to_output_sections): Likewise.
(lang_size_sections_1): Always set last_os for first overlay section.
(lang_leave_overlay): Set sectype to first_overlay_section.
