[PATCH] ARC: Enable automatic support for newer ARC ISA variants (ARCv3)

The syscall TRAP instruction used to be 4 bytes on legacy ARCompact based ARC700 cores. Since then ARCv2 (circa 2014) and the upcoming ARCv3 use the same 2-byte TRAP_S instruction. To ease porting of software to new ISA, special case ARC700. This is the only change needed to get strace working on
