If LD_LIBRARY_PATH is undefined in gargoyle-free before 2009-08-25, the variable will point to the current directory

If LD_LIBRARY_PATH is undefined in gargoyle-free before 2009-08-25, the variable will point to the current directory. This can allow a local user to trick another user into running gargoyle in a directory with a cracked libgarglk.so and gain access to the user's account.
