libdl: Add powerpc large memory and small data support.

- Add support for architecure sections that can be handled by the
  architecture back end.

- Add trampoline/fixup support for PowerPC. This means the PowerPC
  now supports large memory loading of applications.

- Add a bit allocator to manage small block based regions of memory.

- Add small data (sdata/sbss) support for the PowerPC. The support
  makes the linker allocated small data region of memory a global
  resource available to libdl loaded object files.
