I tried to find/fix this one, but ran into another build failure:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=787018
Wherein the maintainer states this package is deprecated and will not be
updated, but will
instead be replaced with a new package (kodi) as soon as kodi is approved FTP
Package: src:xbmc
Version: 2:13.2+dfsg1-4
Severity: normal
Tags: sid stretch
User: debian-...@lists.debian.org
Usertags: ftbfs-gcc-5
Please keep this issue open in the bug tracker for the package it
was filed for. If a fix in another package is required, please
file a bug for the other package
