commit 9f7552cff4367fc58246f72223d7a1de84c660b7

    Fix bad interaction between --relax and tls optimisation
    
    Adding long-branch stubs for __tls_get_addr calls that are optimised
    away is silly.  It also causes assertion failures on newer object files
    that use R_PPC_TLSGD and R_PPC_TLSLD marker relocs, and half-optimised
    (ie. broken) code for older object files.
    
    	PR 16546
    	* elf32-ppc.c (ppc_elf_relax_section): Don't build long-branch
    	stubs for calls to __tls_get_addr that we know will later be
    	optimised away.

    Enable ppc476 workaround for ld -r.
    
    The Linux kernel builds modules using ld -r.  These might need the
    ppc476 workaround, so enable it for ld -r if sections have sufficient
    alignment to tell location within a page.
    
    bfd/
    	* elf32-ppc.c (ppc_elf_relax_section): Enable ppc476 workaround
    	for ld -r, when code sections are sufficiently aligned.
    	* elf32-ppc.h (struct ppc_elf_params): Delete pagesize.  Add
    	pagesize_p2.
    ld/
    	* emultempl/ppc32elf.em (pagesize): New static var.
    	(ppc_after_open_output): Set params.pagesize_p2 from pagesize.
    	(PARSE_AND_LIST_ARGS_CASES): Adjust to use pagesize.

    PR15530, mark symbol in executables if it matches dynamic_list
    
    For powerpc64 as HJ did earlier for other ELF targets, and a tidy.

    	* elf64-ppc.c (ppc64_elf_gc_mark_dynamic_ref): Support
    	--export-dynamic and --dynamic-list marking of symbols.

    	cheap tests first.
