Commit 97bc386fc1 "ARC: Add guard macro to uapi/asm/unistd.h"
inhibited multiple inclusion of ARCH unistd.h. This however hosed the system
since Generic syscall table generator relies on it being included twice,
and in lack-of an empty table was emitted by C preprocessor.
Fix that by allowing one exception to rule for the special case (just
like Xtensa)
