Comment (by bgamari):

 Ahh, never mind. It has little to do with the tar file format. Rather, the
 files which failed in ticket:13974#comment:5 are all included multiple
 times in the bindist. For instance,
 {{{
 $ tar -vtf ghc-8.3.20170720-x86_64-unknown-linux.tar.xz
 ...
 -rwxr-xr-x  0 ben    ben     54184 Jul 20 20:45
 ghc-8.3.20170720/utils/hp2ps/dist-install/build/tmp/hp2ps
 hrwxr-xr-x  0 ben    ben         0 Jul 20 20:45
 ghc-8.3.20170720/utils/hp2ps/dist-install/build/tmp/hp2ps link to
 ghc-8.3.20170720/utils/hp2ps/dist-install/build/tmp/hp2ps
 }}}
 This is no doubt due to a build system bug.
