This converts the fat loader to use spl_load. Some platforms are very
tight on space, so we take care to only include the code we really need.

(no changes since v5)

Changes in v5:
- Rework to load header in spl_load

Changes in v3:
- Fix failing on success

Do we still need this sort of #ifdef? I thought printf() would melt
away without SPL_LIBCOMMON_SUPPORT? I haven't looked though. Also it
isn't related to your patch.

 From what I can tell, printf implementation is orthogonal to LIBCOMMON_SUPPORT.
