[Vineet Gupta]

Please find set of patches to support ARCv2 ISA basis of new HS family of cores
from Synopsys.

v2: Changes since v1:
* 1/4: Updated CFLAGS per latest tools, dropped ASFLAGS, added GLOB to new defconfig
* 2/4: Fixed spello as pointed by Bernhard
* 3/4: Replicated comments from posix_fadvise64.c into posix_fadvise.c
* 4/4: Generlaized UCLIBC_SYSCALL_ALIGN_64BIT handling (vs. only for ARC)

v1: http://lists.uclibc.org/pipermail/uclibc/2015-February/048813.html

Thx,
-Vineet

  ARCv2 ISA support
  posix_fadvise: handle 2 variants for SYSCALL_ALIGN_64BIT
  sync_file_range: fix standard UCLIBC_SYSCALL_ALIGN_64BIT handling
