 Ok, I think it makes sense to do it in the patch for #25304.

 The comment looks good to me. Although, we won't update GCC to 6.2.0
 anymore. Thus, the commit message is wrong. I think we should just close
 this bug an apply the comment about disabling PIE in the upcoming patch
 for #25304.

 I think when this ticket was opened (October 2016), 6.2 was the last
 version. We should probably use 6.4 now.

Comment:

 Okay, I bisected the problem (`PIE` enforcement breaks the compiler) and
 pushed a fix fro review to bug_20301
 (https://gitweb.torproject.org/user/gk/tor-browser-

 The Wheezy compiler is too old for it (generally 4.x).

Comment (by gk):

 This works fine with `hardening-wrapper` settings as we have them in
 Gitian on a Debian testing machine. Additionally, setting
 `DEB_BUILD_HARDENING_PIE=0` for the GCC step in our Gitian build would
 help as well.

 After bumping the GCC version to 6.2.0 due to #13893 building GCC 6.2.0 is
 busted for 64bits in our gitian setup:
