This is a partial backport of this commit with only the 'scope'

refactoring required to have access to the outer scope value

to use with RESOLVE_MAP to implement la_symbind for BIND_NOW.

We do not backport this entire patch because the nested function

changes have significant impact on code generation and would

require furhter backports to support and maintain.

    elf: Avoid nested functions in the loader [BZ #27220]

    dynamic-link.h is included more than once in some elf/ files (rtld.c,

    dl-conflict.c, dl-reloc.c, dl-reloc-static-pie.c) and uses GCC nested

    functions. This harms readability and the nested functions usage

    is the biggest obstacle prevents Clang build (Clang doesn't support GCC

    nested functions).

    The key idea for unnesting is to add extra parameters (struct link_map

    *and struct r_scope_elm *[]) to RESOLVE_MAP,

    ELF_MACHINE_BEFORE_RTLD_RELOC, ELF_DYNAMIC_RELOCATE, elf_machine_rel[a],

    elf_machine_lazy_rel, and elf_machine_runtime_setup. (This is inspired

    by Stan Shebs' ppc64/x86-64 implementation in the

    google/grte/v5-2.27/master which uses mixed extra parameters and static

    variables.)

    Future simplification:

    * If mips elf_machine_runtime_setup no longer needs RESOLVE_GOTSYM,

      elf_machine_runtime_setup can drop the `scope` parameter.

    * If TLSDESC no longer need to be in elf_machine_lazy_rel,

      elf_machine_lazy_rel can drop the `scope` parameter.

    Tested on aarch64, i386, x86-64, powerpc64le, powerpc64, powerpc32,

    sparc64, sparcv9, s390x, s390, hppa, ia64, armhf, alpha, and mips64.

    In addition, tested build-many-glibcs.py with {arc,csky,microblaze,nios2}-linux-gnu

    and riscv64-linux-gnu-rv64imafdc-lp64d.
