This avoids core dump. But the output section type is still SHT_PROGBITS.
The main issue is
static const struct bfd_elf_special_section special_sections_n[] =
{
{ STRING_COMMA_LEN (".noinit"), -2, SHT_NOBITS, SHF_ALLOC +
SHF_WRITE },
{ STRING_COMMA_LEN (".note.GNU-stack"), 0, SHT_PROGBITS, 0 },
{ STRING_COMMA_LEN (".note"), -1, SHT_NOTE, 0 },
{ NULL, 0, 0, 0, 0 }
};
