Remove tilepro-*-linux-gnu support
As from previous discussions [1] this patch removes tileprox-*-linux-gnu support from GLIBC. This patch is a straigthfoward one, which just remove tilepro specific implementation and configurations (no sysdep simplfication or reorganization is done). * README: Remove tilepro-*-linux-gnu from supported architecture. * scripts/build-many-glibcs.py: Likewise. * sysdeps/tile/__tls_get_addr.S (__tls_get_addr): Likewise. * sysdeps/tile/crti.S (PREINIT_FUNCTION): Likewise. * sysdeps/tile/dl-machine.h (ELF_MACHINE_NAME, elf_machine_matches_host, elf_machine_dynamic, elf_machine_load_address, elf_machine_runtime_setup, reloc_howto howto, elf_machine_rela): Likewise * sysdeps/tile/dl-start.S (_start): Likewise. * sysdeps/tile/memcmp.c (DBLALIGN, REVBYTES): Likewise. * sysdeps/tile/memcopy.h (MEMCPY_OK_FOR_FWD_MEMMOVE, MEMCPY_OK_FOR_FWD_MEMMOVE, op_t): Likewise. * sysdeps/tile/nptl/pthread_spin_lock.c (TNS, CMPTNS): Likewise. * sysdeps/tile/nptl/pthread_spin_trylock.c (TNS): Likewise. * sysdeps/tile/nptl/pthread_spin_unlock.c (pthread_spin_unlock): Likewise. * sysdeps/tile/nptl/tls.h (DB_THREAD_SELF): Likewise. * sysdeps/tile/preconfigure: Likewise. * sysdeps/tile/stackguard-macros.h (STACK_CHK_GUARD, POINTER_CHK_GUARD): Likewise. * sysdeps/tile/stackinfo.h (__stackinfo_sub): Likewise. * sysdeps/tile/start.S (_start): Likewise. * sysdeps/tile/tls-macros.h (TLS_GD_OFFSET, TLS_IE_OFFSET, _TLS_LE): Likewise. * sysdeps/tile/sysdep.h (REGSIZE): Likewise. (LD, LD4U, ST, ST4, BNEZ, BEQZ, BEQZT, BGTZ, CMPEQI, CMPEQ, CMOVEQZ, CMOVNEZ): Remove. * sysdeps/unix/sysv/linux/tile/bits/environments.h (__ILP32_OFF32_CFLAGS, __ILP32_OFFBIG_CFLAGS, __ILP32_OFF32_LDFLAGS, __ILP32_OFFBIG_LDFLAGS, __LP64_OFF64_CFLAGS, __LP64_OFF64_LDFLAGS): Likewise. * sysdeps/tile/wordcopy.c (DBLALIGN): Likewise. * sysdeps/tile/tilepro/Implies: Remove file. * sysdeps/tile/tilepro/atomic-machine.h: Likewise. * sysdeps/tile/tilepro/bits/wordsize.h: Likewise. * sysdeps/tile/tilepro/memchr.c: Likewise. * sysdeps/tile/tilepro/memcpy.S: Likewise. * sysdeps/tile/tilepro/memset.c: Likewise. * sysdeps/tile/tilepro/memusage.h: Likewise. * sysdeps/tile/tilepro/rawmemchr.c: Likewise. * sysdeps/tile/tilepro/strchr.c: Likewise. * sysdeps/tile/tilepro/strchrnul.c: Likewise. * sysdeps/tile/tilepro/strlen.c: Likewise. * sysdeps/tile/tilepro/strrchr.c: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/Implies: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/c++-types.data: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/jmp_buf-macros.h: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/ld.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/ldconfig.h: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libBrokenLocale.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libanl.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libcrypt.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libdl.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libnsl.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libpthread.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libresolv.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/librt.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libthread_db.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libutil.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/register-dump.h: Likewise. * sysdeps/unix/sysv/linux/tile/sysconf.c (linux_sysconf): Remove tilepro mention in comment.
