eac7440d80 AVR: Only set link-relax elf flag when appropriate.
The AVR target uses a bit in the elf header flags to indicate if the
object was assembled ready for linker relaxation.  Previously this flag
was always set, even when the object was not assembled ready for linker
relaxation.

This patch moves setting of the flag into the assembler, and sets it
only when the assembler is preparing the file for linker relaxation.

	EF_AVR_LINKRELAX_PREPARED unconditionally.

12b2843a6b Use a symbol flag bit to mark linker defined symbols
Trying to use the SEC_LINKER_CREATED section flag to determine whether
a symbol is linker defined fails to work on targets like alpha that
define special SEC_COMMON sections.  These might contain symbols that
originated in an object file.

6cabe1ea46 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.

This change to elf_parse_notes is the culprit:

e00e81980c Don't return DW_AT_name for function name in C++
DW_AT_name for functions typically just contains the base function
name, so lacks namespace, class and parameter information.  It would
be possible to extract all these from the DWARF, but at a considerable
complication of the parser in dwarf2.c, and then you'd need to mangle
it all together.  Much simpler is to look up the actual symbol.  This
patch does that, avoiding the extra symbol lookup when the language
doesn't do name mangling.

3972882e52 Add _bfd_elf_ifunc_get_synthetic_symtab
In i386 and x86-64 binaries with ifunc, relocations against .got.plt
section may not be in the same order as entries in PLT section.  This
patch adds _bfd_elf_ifunc_get_synthetic_symtab.  It takes a function
pointer which returns an array of PLT entry symbol values.  It calls
the function pointer to get the PLT entry symbol value array indexed
by relocation index, instead of calling plt_sym_val on each relocation
index.

This patch reverts the change in elf_x86_64_check_relocs and the partial

in PIE for relocs against symbols which turn out to need copy relocs.

538baf8b7e [MIPS] When calculating a relocation using an undefined weak symbol don't check for overflow.
In MIPS the relocation calculation only ignores the overflow checks for undefined
weak symbols on relocations associated with j/jal.   This patch extends this to
the relocations used by the: b* instructions; pc/gp relative symbol offsets; and the
lwpc/ldpc MIPS r6 instructions.
