    tile: Check SHARED instead PIC for SYSCALL_ERROR_NAME
    
    For static PIE code, PIC is defined and SHARED is undefined.  We

    	* sysdeps/unix/sysv/linux/tile/sysdep.h (SYSCALL_ERROR_NAME):
    	Check SHARED instead PIC.

    Add --enable-static-pie configure option to build static PIE [BZ #19574]
    
    Dynamic linker, ld.so, is a standalone program which can be loaded at
    any address.  This patch adds a configure option, --enable-static-pie,
    to embed the part of ld.so in static executable to create static position
    independent executable (static PIE).  A static PIE is similar to static
    executable, but can be loaded at any address without help from a dynamic
    linker.  When --enable-static-pie is used to configure glibc, libc.a is
    built as PIE and all static executables, including tests, are built as
    static PIE.  The resulting libc.a can be used together with GCC 8 or
    above to build static PIE with the compiler option, -static-pie.  But
    GCC 8 isn't required to build glibc with --enable-static-pie.  When an
    older GCC is used to build glibc with --enable-static-pie, proper input
    files are passed to linker to create static executables as static PIE,
    together with "-z text" to prevent dynamic relocations in read-only
    segments, which are allowed in static PIE.
    
    Static PIE can work on all architectures which support PIE, provided
    
    1. Target must support accessing of local functions without dynamic
    relocations, which is needed in start.S to call __libc_start_main with
    function addresses of __libc_csu_init, __libc_csu_fini and main.  All
    functions in statice PIE are local functions.
    2. start.S is updated to check PIC instead SHARED for PIC code path and
    avoid dynamic relocation, when PIC is defined and SHARED isn't defined,
    to support static PIE.  Patches are submitted for aarch64, arm, hppa,
    m68k, microblaze and sparc.
    3. All assembly codes are updated check PIC instead SHARED for PIC code
    path to avoid dynamic relocations in read-only sections.
    4. All assembly codes are updated check SHARED instead PIC for static
    symbol name.  A patch is submitted for tile.
    5. elf_machine_load_address in dl-machine.h are updated to support static
    PIE.  Patches are submitted for aarch64, arm, hppa, ia64, m68k, microblaze,
    mips, nios2, powerpc, s390, sh, sparc and tile.
    
    NB: When glibc is built with GCC defaulted to PIE, libc.a is compiled
    with -fPIE, regardless if --enable-static-pie is used to configure glibc.
    When glibc is configured with --enable-static-pie, libc.a is compiled
    with -fPIE, regardless wether GCC defaults to PIE or not.  The same libc.a
    can be used to build both static executable and static PIE.  There is no
    need for separate PIE copy of libc.a.
    
    Linker requirements to build glibc with --enable-static-pie:
    
    1. Linker supports --no-dynamic-linker to remove PT_INTERP segment from
    static PIE.
    2. Linker can create working static PIE.  The x86-64 linker needs the
    fix for
    
    https://sourceware.org/bugzilla/show_bug.cgi?id=21782
    
    Binutils 2.29 or above are OK for x86-64.  But linker status for other
    targets need to be verified.
    
    Tested on i686 and x86-64.

commit 029e1197a4e0ace7a0ad18a00540d114926a524b
Author: H.J. Lu <hjl.tools@gmail.com>

    ld.so: Replace (&bootstrap_map) with BOOTSTRAP_MAP
    
    (&_dl_main_map) is used instead of (&bootstrap_map) to bootstrap static
    PIE.  Define BOOTSTRAP_MAP with (&_dl_main_map) to avoid hardcode to
    (&bootstrap_map).
    
    	* elf/rtld.c (BOOTSTRAP_MAP): New.
    	(RESOLVE_MAP): Replace (&bootstrap_map) with BOOTSTRAP_MAP.
    	* sysdeps/hppa/dl-machine.h (ELF_MACHINE_BEFORE_RTLD_RELOC):
    	Likewise.
    	* sysdeps/ia64/dl-machine.h (ELF_MACHINE_BEFORE_RTLD_RELOC):
    	Likewise.
    	* sysdeps/mips/dl-machine.h (ELF_MACHINE_BEFORE_RTLD_RELOC):
    	Likewise.
