Take #2 on mainlining strace support for ARC (last one was 4.6 based back
in March 2011)
http://sourceforge.net/p/strace/mailman/message/27210168/
ARC Linux kernel port was merged in mainline 3.9, so hopefully strace
can now be merged too.
The syscall ABI is asm-generic/unistd.h based (so no legacy syscalls),
hence very similar to metag port.
test/* all seem to work well.
