61a4ab8966 binfmt: migrate to SPDX identifier
Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

675f775494 log messages of binfmt are very much.
this is to adjust levels of a few of them based on debugging
experiences. These non-critical logs were marked as errors. So we
likely can adjust them as warnings so that real errors can
stand out easily.

it's better to allocate the buffer just before really use it.

7c003162a6 libelf/libelf_symbols.c: Fix compilation warning about void* arithmetics
Fixes minor issue with a trace (build failure with -Werror):
libelf/libelf_symbols.c:310:41: error: pointer of type 'void *' used in arithmetic [-Werror=pointer-arith]
  310 |               (uintptr_t)(sym->st_value + symbol->sym_value));

c9db653c8d symtabs: improve handling of symbol lookups
When CONFIG_SYMTAB_ORDEREDBYNAME is selected most code will use
the ordered search function. When it is not selected no code will
use the ordered search function. This change merges the two
functions and varies its behaviour based on the config setting,
such that all callers can simply call the one search function
and get the best behaviour.

An additional configuration option allows leading underscores to
be stripped from symbols being relocated in loaded objects. This
allows toolchains which prefix C symbol with underscores to make
loadable ELF objects.

81f1133174 ELF64 support (#220)
* include: Introduce elf64.h and elf.h

    Added elf64.h for 64bit ELF support and moved common definitions
    from elf32.h to elf.h. Also introduced Elf_xxx to be used in
    common libraries such as binfmt.

  * binfmt, include, modlib, module: Add support for ELF64

    Elf_xxx must be used instead of Elf32_xxx to support ELF64.
    To use ELF64, CONFIG_ELF_64BIT must be enabled.

  * binfmt, modlib: Add support for relocate address

  * arch: risc-v: Add include/elf.h

  * libs: machine: Add risc-v related files.

    NOTE: Currently only supports ELF64

  * boards: maix-bit: Add elf and posix_spawn configurations

  * boards: maix-bit: Add support for module configuration
