x86-64: Allocate input section memory if needed
When --no-keep-memory is used, the input section memory may not be cached. Allocate input section memory for -z pack-relative-relocs if needed. bfd/ PR ld/29939 * elfxx-x86.c (elf_x86_size_or_finish_relative_reloc): Allocate input section memory if needed. ld/ PR ld/29939 * testsuite/ld-elf/dt-relr-2i.d: New test.
