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.

Updates #3687
Updates #3685
  • Property mode set to 100644
