PR ld/14207
* elf.c (assign_file_positions_for_load_sections): Remove assertions
that only PT_LOAD headers include file header and section headers.
(assign_file_positions_for_non_load_sections): Similarly don't
assert PT_GNU_RELRO header does not include file and section headers.
Compare first section vma rather than PT_LOAD p_vaddr against
relro_start when looking for PT_LOAD covering PT_GNU_RELRO. Replace
abort with assertion.
