- Avoid segmentation fault in "join -i" with long line input (bnc#798541, VUL-1)

* src/join.c: Instead of usig unreliable alloca() stack allocation,
    use heap allocation via xmalloc()+free().
    (coreutils-i18n.patch, from Philipp Thomas <pth@suse.de>)
- Avoid segmentation fault in "sort -d" and "sort -M" with long line input
