-fstack-protector[-all] causes SEGV with small programs calling only a noreturn func

gcc generates a stack protector prologue accessing TLS, but not the epilogue which would pull in the TLS init code, when a noreturn func like exit() is called.
this causes small configure checks to fail when -fstack-protector[-all] is active.

IIRC this was fixed a while ago, but never closed.
