 Replying to [comment:3 boklm]:
 > An other option is to check for SSE2 support only if `/proc/cpuinfo` is
 readable, and if not assume that SSE2 is available.

 This is what the patch in branch `bug_31968` is doing:
 https://gitweb.torproject.org/user/boklm/tor-browser-
 build.git/commit/?h=bug_31968&id=6cf4e6eabc5eb559baf9721a3caf0544b7480093

 @cypherpunks: could you check if applying this change to your `Browser
 /start-tor-browser` script solves the issue?
