That's nothing for ESR 60. We stick to 6.x for Tor Browser 8.

We could get -fwrapv back for our debug builds if we switched to GCC 8.x (see: #27597). As a data point: I've been compiling (and using) some custom Tor Browser with GCC 8.x for a while now and did not run into any issues. Thus, we might consider 8.x sufficiently stable to switch to it in particular when preparing for eser68.
