PR other/77609: Let the assembler choose ELF section types for miscellaneous
named sections

gcc/
        PR other/77609
        * varasm.c (default_section_type_flags): Set SECTION_NOTYPE for
        any section for which we don't know a specific type it should have,
        regardless of name.  Previously this was done only for the exact
        names ".init_array", ".fini_array", and ".preinit_array".
        (default_elf_asm_named_section): Add comment about
        relationship with default_section_type_flags and SECTION_NOTYPE.
        (get_section): Don't consider it a type conflict if one side has
        SECTION_NOTYPE and the other doesn't, as long as neither has the
        SECTION_BSS et al used in the default_section_type_flags logic.
