On boards with size restrictions, 1-2k can be a significant fraction of
the binary size. Add a new SPL version of SYS_MALLOC_RUNTIME_INIT and
enable it by default.

+ Initialize malloc's internal data structures at SPL runtime, rather
+ than at compile-time. This is necessary if relocating the malloc arena
+ from a smaller static memory to a large DDR memory. It can also reduce
