internal: Fix caching issues with config variants. Before, changing config variant values could incorrectly re-use a previously cached config as long as there were the same number of variants. Now we build a stricter cache hash based on the actual values.

#!/bin/sh

CHEF_DIR=`dirname $0`
if `hash readlink 2>&-`; then
    LINKED_EXE=`readlink $0`
    if [ -n "$LINKED_EXE" ]; then
        CHEF_DIR=`dirname $LINKED_EXE`
    fi
