+Description: Fix build failure with newer glibc
+ Currently the package FTBFS because of errors re: the deprecated __malloc_hook
+ etc. usage. The fix is basically taken from 'upstream' - I mention 'upstream'
+ as right now it's not really clear which repository can be considered upstream
+ for this project.
+Origin: upstream, https://github.com/gordan-bobic/zfs-fuse/commit/9d554eb82861d449f5e86aa6c272da6dd91377a8
