Comment (by bgamari):

 I have done a bit of characterisation of the issue since I fear we simply
 don't have time at this point to come up with a proper solution for 17.10.

 ||= Distribution =||= binutils version =||= glibc version =||= Affected
 =||
 || Ubuntu Wily (15.10)   ||      ||      ||     ||
 || Ubuntu Xenial (16.04) || 2.26 || 2.23 || Yes ||
 || Ubuntu Zesty (17.04)  || 2.28 || 2.24 || No  ||
 || Debian Jessie (9.0)   || 2.28 || 2.24 || No  ||
 || Ubuntu Artful (17.10) || 2.29 || 2.26 || No  ||
