Comment (by arthuredelstein):

 Here's my patch for review. I would suggest we adding it after we have
 transitioned to rbm builds:

 I tried building TBB with `-fstack-protector-strong` on mingw-w64 but so
 far ran into
 errors]. However, a Windows Tor Browser built with this patch (using
 `-fstack-protector-all`) doesn't seem subjectively slower to me, so I
 would suggest trying this on the alpha, at least until we have a solution
 for `-fstack-protector-strong` on mingw-w64.
