Alan Modra 9495b2e66f Correct fscanf char field count
%<number>s as an fscanf format does not include the trailing NULL.
PATH_MAX does include the trailing NULL.

Terry Guo 70e99720f9 Make the linker return an error status if it fails to merge ARM binaries with
different architecture tags.  Add a test case to make sure that this works,
and update readelf so that it will not seg-fault when trying to display the
attributes of binaries with invalid architecture tags.

	* elf32-arm.c (elf32_arm_merge_eabi_attributes): Return false if
	failed to merge.

	* ld-arm/attr-merge-arch-2.d: New test case.
	* ld-arm/attr-merge-arch-2a.s: New test case source file.
	* ld-arm/attr-merge-arch-2b.s: Likewise.
	* ld-arm/arm-elf.exp: Run new test case.

	* readelf.c (display_arm_attribute): Use unsigned int type for
	tag, val and type variables.

Kuan-Lin Chen 40c7a7cb74 NDS32/opcodes: Add audio ISA extension and modify the disassemble implemnt.
First, add nds32 audio ISA extension including opcodes and registers.
Second, redesign the disassemble implement.
The original disassemble decode instruction opcode using switch-case.
It is hard to synchronize when adding new instructions.
Therefore, the new implement reuses nds32_opcodes to dump the instructions.

Alan Modra e8910a83af Replace DT_PPC_TLSOPT with DT_PPC_OPT.
This removes the DT_PPC_TLSOPT/DT_PPC64_TLSOPT dynamic tag and replaces
it with DT_PPC_OPT/DT_PPC64_OPT tag to provide the same functionality
and more.  This isn't backwards compatible, but the TLSOPT tag hasn't
been used since the tls optimisation support was never submitted to
glibc.
