From: Peilin Ye <peilin.ye@bytedance.com>
objcopy's --only-keep-debug option has been broken for ELF files since
commit 8c803a2dd7d3.
1. binutils/objcopy.c:setup_section() marks non-debug sections as
SHT_NOBITS, then calls bfd_copy_private_section_data();
2. If ISEC and OSEC share the same section flags,
bfd/elf.c:_bfd_elf_init_private_section_data() restores OSEC's
section type back to ISEC's section type, effectively undoing
"make_nobits".
* objcopy.c (setup_section): Act on make_nobits after calling
bfd_copy_private_section_data.

This was needed by ancient versions of automake, but that hasn't been
the case since at least automake-1.5, so punt this from the tree.

binutils/NEWS says of the change in --process-links semantics:
If other debug section display options are also enabled (eg
--debug-dump=info) then the contents of matching sections in both the main
file and the separate debuginfo file *will* be displayed. This is because in
most cases the debug section will only be present in one of the files.
Implying that debug info is dumped without --process-links. Indeed
that appears to be the case for readelf. This does the same for
objdump.
PR 28029
* objdump.c (dump_bfd): Do not exit early when !is_mainfile
&& !processlinks, instead just exclude non-debug output.
(dump_dwarf): Add is_mainfile parameter and pass to
dump_dwarf_section.
(dump_dwarf_section): Only display debug sections when
!is_mainfile and !process_links.

PowerPC64 takes a more traditional approach to DT_RELR than x86. Count
relative relocs in check_relocs, allocate space for them and output in
the usual places but not doing so when enable_dt_relr. DT_RELR is
sized in the existing ppc stub relaxation machinery, run via the
linker's ldemul_after_allocation hook. DT_RELR is output in the same
function that writes ppc stubs, run via ldemul_finish.
This support should be considered experimental.

As pre-approved by Alan in
https://sourceware.org/pipermail/binutils/2021-September/118019.html
and I believe people have run into getting testsuite failures for
test-environments with "long" directory names, at least once more
since that time. Enough. I grepped the gas, binutils and ld
testsuites for "CU:" to catch target-specific occurrences, but I
noticed none. I chose to remove "CU:" on the objdump tests instead of
changing options to get the wide format, so as to keep the name of the
test consistent with actual options; but added it to the readelf
options for the gas test as I believe the "CU:" format is preferable.
Tested for cris-elf and native x86_64-pc-linux-gnu.
binutils:
* dwarf.c (display_debug_lines_decoded): Don't check the
string length of the directory, instead emit the "CU: dir/name"
format only if wide output is requested.
* testsuite/binutils-all/dw5.W, testsuite/binutils-all/objdump.WL:
Adjust accordingly.
gas:
* testsuite/gas/elf/dwarf-5-loc0.d: Add -W to readelf options.

This adds support for efi-*-aarch64 by virtue of adding a new PEI target
pei-aarch64-little. This is not a full target and only exists to support EFI
at this time.
This means that this target does not support relocation processing and is mostly
a container format. This format has been added to elf based aarch64 targets
such that efi images can be made natively on Linux.
However this target is not valid for use with gas but only with objcopy.
With these changes the resulting file is recognized as an efi image by
third party tools:

A missing "return" resulted in this non-ELF fail:
x86_64-w64-mingw32 +FAIL: debuginfod (create separate debug info file)
Also, the debuginfod I have installed does not appear to handle
non-native ELF objects, so only run the test when native.
* testsuite/binutils-all/debuginfod.exp: Don't run test unless
native ELF.
