Remove linker command line options from the SPL makefile that force the inclusion of unreferenced command code from linked object files. As commands are not used in the SPL, these options resulted in an unnecessary increase in the image size, in addition to introducing the possibility of tricky link errors in the case where the command code contained symbols that were not resolved by linking in the limited objects compiled in the SPL build.
