Helge told "I prefer to keep the warning for rseq for now.
It reminds me that we still may want the rseq syscall.
If the warning is a problem, you may simply add the __IGNORE_rseq define."

I chose this option; I feel it looks clean
"# rseq requires an architecture specific implementation" in syscall.tbl
hopefully remind him to add rseq syscall implementation in this architecture.
