I have enabled the macro elf_backend_create_dynamic_sections in the
elf32-xxxx.c BFD support file and I am able to make progress still
with failures.

Can anyone describe the meaning of enabling the following macros ?

#define elf_backend_rela_normal
#define elf_backend_can_refcount
#define elf_backend_plt_readonly
#define elf_backend_want_got_sym
#define elf_backend_want_plt_sym
#define elf_backend_want_dynrelro
#define elf_backend_got_header_size
#define elf_backend_want_got_plt
