-Most temp file directories need to be hardened against execution, but
-libffi needs execute privileges.  Add a libffi-specific temp directory
-that can be set up by sysadmins as needed with suitable permissions.
-This both ensures that libffi will have a valid temp directory to use
-as well as preventing attempts to access other directories.
