    Add symbols for global entry stub, and report stats
    
    The undefined function symbols (with non-zero value) on global entry
    stubs are discarded by objdump when disassembling, so give objdump
    another symbol to mark the stubs.
    
    Also fixes a couple of bugs:
    - entry_section was set to .opd for ELFv2, which meant a hard error
      rather than a warning when _start wasn't defined.
    - global entry stubs were not built if they were the only type of
      stub in an executable.
    
    bfd/
    	* elf64-ppc.c (ppc_stub_type): Add ppc_stub_global_entry.
    	(struct ppc_link_hash_table): Increase size of stub_count array.
    	(build_global_entry_stubs): Emit symbol on global entry stub.
    	(ppc64_elf_build_stubs): NULL check htab->brlt.  Add global entry
    	stub stats.
    ld/
    	* emultempl/ppc64elf.em (stub_added): Delete.
    	(gld${EMULATION_NAME}_finish): Call ppc64_elf_build_stubs even when
    	none of the usual stubs have been added.  Only change entry_section
    	for ELFv1.

    Don't include sys/param.h
    
    sys/param.h on recent versions of powerpc glibc ends up including
    asm/elf.h via asm/sigcontex.h.  asm/elf.h defines R_PPC_* and R_PPC64_*
    macros, which clash with our include/elf/ppc.h and include/elf/ppc64.h.
    It turns out that no current source uses LD_PATHMAX, so there is no
    need for limits.h or sys/param.h, except for one occurrence of UINT_MAX.
    I don't have a quarrel with limits.h, but it seems unnecessary just
    for UINT_MAX.
    
    	* sysdep.h: Don't include limits.h and sys/param.h.  Don't
    	include unistd.h twice.
    	(LD_PATHMAX): Don't define.
    	* ldlang.c (lang_common): Don't use UINT_MAX.

    Linker foreign output format support for PowerPC64 ELFv2
    
    Makes the ld srec tests pass.  Uses a horrible scan through symbols to
    find ELF fields for symbol definitions, but the generic linker doesn't
    offer anything better.  Might be slow.  Anyway, sane people will link
    to ELF output then objcopy to convert formats.
    
    	* elf64-ppc.c (abiversion, set_abiversion): Move earlier.
    	(ppc64_elf_branch_reloc): Adjust addend for ELFv2 local offset.
    	(ppc64_elf_set_toc): Set ".TOC." symbol value when using
    	generic linker.
    	(ppc64_elf_relocate_section): Disable ELFv2 function entry
    	optimisation when --traditional-format.
