Some stuff aparently didn't get committed which was from before the new repository was created.

Browse source 
SConscript:
    There is a new SConscript in the arch/alpha directory which has the alpha specific files. To add files for an arch, a similar file should be created.
arch/isa_parser.py:
    The isa parser now supports include directives. These are done with ##include
build/SConstruct:
    The target directory is passed on so that the architecture specific SConscript can have it. Also, sparc was added as a valid architecture type.
arch/alpha/SConscript:
    This SConscript adds the alpha specific source
arch/sparc/isa_desc/operands.h:
    This sets up the operand types that the sparc isa uses
arch/sparc/isa_traits.cc:
    Implementation of sparc specific things, like a register file with windows
build/build_options/default/SPARC_SE:
    The default options for a sparc syscall emulation build.
