How to output flags in C in the same format as the objdump command does?

Why don't you look at the code ?

static void
dump_bfd_header (bfd *abfd)
{
  char *comma = "";

  printf (_("architecture: %s, "),
          bfd_printable_arch_mach (bfd_get_arch (abfd),
                                   bfd_get_mach (abfd)));
  printf (_("flags 0x%08x:\n"), abfd->flags & ~BFD_FLAGS_FOR_BFD_USE_MASK);

#define PF(x, y)    if (abfd->flags & x) {printf("%s%s", comma, y); comma=", ";}
  PF (HAS_RELOC, "HAS_RELOC");
  PF (EXEC_P, "EXEC_P");
  PF (HAS_LINENO, "HAS_LINENO");
  PF (HAS_DEBUG, "HAS_DEBUG");
  PF (HAS_SYMS, "HAS_SYMS");
  PF (HAS_LOCALS, "HAS_LOCALS");
  PF (DYNAMIC, "DYNAMIC");
  PF (WP_TEXT, "WP_TEXT");
  PF (D_PAGED, "D_PAGED");
  PF (BFD_IS_RELAXABLE, "BFD_IS_RELAXABLE");
  printf (_("\nstart address 0x"));
  bfd_printf_vma (abfd, abfd->start_address);
  printf ("\n");
}
