ld: Limit cache size and add --max-cache-size=SIZE
When link_info.keep_memory is true, linker caches the relocation information and symbol tables of input files in memory. When there are many input files with many relocations, we may run out of memory. Add --max-cache-size=SIZE to set the maximum cache size. bfd/ PR ld/18028 * bfd.c (bfd): Add alloc_size. * elf-bfd.h (_bfd_elf_link_info_read_relocs): New. * elf32-i386.c (elf_i386_check_relocs): Use _bfd_link_keep_memory. Update cache_size. * elf64-x86-64.c (elf_x86_64_check_relocs): Likewise. * elflink.c (_bfd_elf_link_read_relocs): Renamed to ... (_bfd_elf_link_info_read_relocs): This. Update cache_size.
