Filled out the object file loader so it can load object files for several OSs and architectures.
SConscript: Added ./libelf as an include search directory. There might be a better spot for this than where I put it. arch/SConscript: Combined the linux_process.h and tru64_process.h into process.h. This allows each ISA to support processes from arbitrary OSs. arch/alpha/SConscript: Added process.cc as a source file. It provides an implementation of createProcess, which takes an object_file object and creates the appropriate process object, or dies. base/loader/elf_object.cc: Actually extract the OS and architecture from the elf file, rather than always guessing Alpha and Linux. base/loader/object_file.hh: Added constants for SPARC, MIPS, and Solaris, and changed the include for the Addr type. sim/process.cc: Pushed creation of specific process objects into the ISA specific code. --HG-- extra : convert_revision : b4754e7ca8328672d07e1394c4d162e199606b53
