CONFIGURE_MAXIMUM_THREAD_LOCAL_STORAGE_SIZE
Add this application configuration option. This configuration option can be
used to reserve space for the dynamic linking of modules with thread-local
storage objects.
Add RTEMS_TASK_STORAGE_ALIGNMENT to define the minium alignment of a
thread-local storage size.
Update #4074.
