dynrelro section for read-only dynamic symbols copied into executable
...
Variables defined in shared libraries are copied into an executable's
.bss section when code in the executable is non-PIC and thus would
require dynamic text relocations to access the variable directly in
the shared library. Recent x86 toolchains also copy variables into
the executable to gain a small speed improvement.
The problem is that if the variable was originally read-only, the copy
in .bss is writable, potentially opening a security hole. This patch
cures that problem by putting the copy in a section that becomes
read-only after ld.so relocation, provided -z relro is in force.
The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.

Return void from linker callbacks
...
The ldmain.c implementation of these linker callback functions always
return true, so any code handling a false return is dead. What's
more, some of the bfd backends abort if ever a false return is seen,
and there seems to be some confusion in gdb's compile-object-load.c.
The return value was never meant to be "oh yes, a multiple_definition
error occurred", but rather "out of memory or other catastrophic
failure".
This patch removes the status return on the callbacks that always
return true. I kept the return status for "notice" because that one
does happen to need to return "out of memory".

Set dynamic tag VMA and size from dynamic section when possible
...
Rather than searching the output for a specific named section, it's

Add output_type to bfd_link_info
...
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

Fallout from recent bfd_reloc_outofrange changes
...
Commit ec93045b
and cd21f5da
introduced a large number of tic4x and
tic54x regressions, due to the new checks being wrong for targets
with octets_per_byte != 1. To fix that I introduced a new
bfd_get_section_limit_octets and performed the check on octets rather
than byte adresses, reducing the number of bfd_octets_per_byte calls.
bfd_octets_per_byte is rather expensive..
I then wondered why the same bfd_reloc_outofrange check added to
bfd_perform_relocation wasn't also added to bfd_install_relocation.
The two functions are virtually identical and ought to remain that
way. However, adding the same check to bfd_install_relocation
resulted in ld-elf "FAIL Link eh-group.o to eh-group" on many ELF
targets, including x64_64-linux. The reason being that eh-group.o
has NONE relocs at the end of a section, and most targets give NONE
relocs a non-zero size. So if we are to keep the new outofrange
check it appears that NONE relocs must have a zero size.

Copy relocations against protected symbols
...
Copy relocs are used in a scheme to avoid dynamic text relocations in
non-PIC executables that refer to variables defined in shared
libraries. The idea is to have the linker define any such variable in
the executable, with a copy reloc copying the initial value, then have
both the executable and shared library refer to the executable copy.
If the shared library defines the variable as protected then we have
two copies of the variable being used.

Don't call bfd_link_hash_table_free
...
Freeing the linker hash table is a royal pain. It can't be freed
before the _bfd_write_contents call in bfd_close, because some target
bfd_write_contents functions access the hash table. It can't be freed
after bfd_close either, since bfd_alloc memory holding side data
structures disappears (PR17047). Clearly the only place it can be freed
is actually in bfd_close. This patch doesn't do that, but kills off
the existing means of freeing the hash table via a bfd target xvec call.
