Not before linux-c6- infra ports land. TBB directly depends on
glibc-2.11 symbol unlike www/linux-firefox. One could try hacking ELF
sections to force longjmp@GLIBC_2.0 instead (undo FORTIFY_SOURCE).

$ ./start-tor-browser

Launching Tor Browser Bundle for Linux in .

TBB wasn't designed to be installed as a system package. I've tried to
force it to but ended up with an invariable[1] symlink preventing the
installed package to be used by multiple users. The symlink is supposed
to point to a copy of mutable user data and destroyed together with the
data upon package deinstallation (mimic standalone).

  /usr/local/lib/linux-tor-browser/Data -> /tmp/linux-tor-browser

Besides, there's a related issue where running multiple instances of TBB
still requires manually adjusting port numbers in Tor config and
about:config preferences of TorLauncher and TorButton.

[1] alas, no variant/magic symlinks on FreeBSD yet
