Elevate .text.syscall to .privileged It turns out adding OpenBSD msyscall() origin verification broke the --ftrace flag. The executable needs to issue raw syscalls while it's rewriting itself. So they need to be in the same section, and that's just plain simpler too.

Always initialize thread local storage We had previously not enabled TLS in MODE=tiny in order to keep the smallest example programs (e.g. life.com) just 16kb in size. But it was error prone doing that, so now we just always enable it because this change uses hacks to ensure it won't increase life.com's size. This change also fixes a bug on NetBSD, where signal handlers would break thread local storage if SA_SIGINFO was being used. This looks like it might be a bug in NetBSD, but it's got a simple workaround.
