Commit0f54df53d2("build: Remove gnulib") introduced a bug when I rewrote existing code that used gnulib areadlink(). A missing "continue" statement on the path where fstatat(2) failed caused fall-through to the case where it tries to use malloc(3) on the value from the uninitialized stat buf. This caused a huge amount of memory to be allocated, invoking the oom-killer inside the appliance.
