5474d94f03 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.

	bfd/
	* elf32-arm.c (a8_erratum_fix): Add st_type field to record the
	destination mode of the a8 stub.
	(elf32_arm_link_hash_table): Add top_id field.
	(elf32_arm_link_hash_table_create): Initialize top_id.
	(arm_type_of_stub): Update prototype, st_type can now be updated
	by this function. Actual destination address in case of PLT is
	computed here, to help factorizing code.
	(elf32_arm_stub_name): Update prototype, use stub_type additional
	parameter to build stub name.
	(elf32_arm_get_stub_entry): Update prototype, use stub_type
	additional parameter to build stub entry.
	(arm_build_one_stub): Use bfd_put_16/bfd_put_32 instead of
	put_thumb_insn/put_arm_insn as BE8 encoding is now handled later.
	Call elf32_arm_final_link_relocate to process all in-stub
	relocations.
	(elf32_arm_setup_section_lists): Update top_id.
	(cortex_a8_erratum_scan): Record stub destination mode.
	(elf32_arm_size_stubs): Update call to arm_type_of_stub according
	to new prototype.
	(elf32_arm_final_link_relocate): Enable processing of in-stub
	REL32 relocations. Rely on arm_type_of_stub to detect if a stub is
	needed, enabling code factorization.
	(elf32_arm_final_link): Process stub sections.
	(elf32_arm_output_map_sym): Add entry to code/data map.

	ld/testsuite/
	* ld-arm/arm-elf.exp: Change .text start address for
	farcall-thumb-arm tests. Add v4t variant for farcall-mixed-lib
	test.
	* ld-arm/farcall-mixed-lib-v4t.d: New test.
	* ld-arm/farcall-mixed-lib1.s: Don't force armv5t.
	* ld-arm/farcall-mixed-lib2.s: Likewise.
	* ld-arm/arm-call.d: Update expected results.
	* ld-arm/cortex-a8-far.d: Likewise.
	* ld-arm/farcall-group-size2.d: Likewise.
	* ld-arm/farcall-group.d: Likewise.
	* ld-arm/farcall-mix.d: Likewise.
	* ld-arm/farcall-mix2.d: Likewise.
	* ld-arm/farcall-mixed-app-v5.d: Likewise.
	* ld-arm/farcall-mixed-app.d: Likewise.
	* ld-arm/farcall-mixed-lib.d: Likewise.
	* ld-arm/farcall-thumb-arm.d: Likewise.
	* ld-arm/farcall-thumb-arm-blx.d: Likewise.
	* ld-arm/farcall-thumb-arm-pic-veneer.d: Likewise.
	* ld-arm/farcall-thumb-arm-blx-pic-veneer.d: Likewise.
	* ld-arm/farcall-thumb-arm.s: Update test. Add a new call to
	potentially generate different types of stubs.
