3e19fb8f99 Delay setting up compressed debug section names
When we set up st_name for output section name in elf_fake_sections, we
don't know if the compressed DWARF debug section will be smaller. We may
end up with compressed DWARF debug sections which are bigger than the
uncompressed ones.  This patch delays setting up st_name for output DWARF
debug section to _bfd_elf_assign_file_positions_for_non_load which will
compress the output debug section.  We also postpone placement of shstrtab
section after DWARF debug sections have been compressed.  The net effect
is .shstrtab section is now placed after .symtab and .strtab sections.

Change compressed input debug section name for objdump is very confusing.

e97029632c Always set up sh_name in assign_section_numbers
commit 9ad5cbcfb23cb74d34bd04f88f4e47c0f5de5155 added the initial support
for more than 64k ELF sections with holes for reserved section indices in
section header table and set entries of reserved section indices in
section header table to index 0:

   for (secn = 1; secn < section_number; ++secn)
-    i_shdrp[secn]->sh_name = _bfd_elf_strtab_offset (elf_shstrtab (abfd),
-                                                    i_shdrp[secn]->sh_name);
-
+    if (i_shdrp[secn] == NULL)
+      i_shdrp[secn] = i_shdrp[0];
+    else
+      i_shdrp[secn]->sh_name = _bfd_elf_strtab_offset (elf_shstrtab (abfd),
+							i_shdrp[secn]->sh_name);

commit 4fbb74a6055f7d48f09c44064073d3b1e99c6642 removed holes in section
header table.  Check for i_shdrp[secn] == NULL is no longer needed now.
