start towards getting m5 endian compliant

base/inifile.cc:
    Added mac os support and fixed a bug, on error we need to exit the
    child process not return
base/intmath.hh:
    gcc on macos wanted a seperate function for the size_t type
base/loader/elf_object.cc:
    I'm not sure why this works under linux because it seems to return
    the wrong value.
base/stats/text.cc:
    added define/include for mac os x
cpu/exec_context.hh:
cpu/simple_cpu/simple_cpu.cc:
    added endian conversion code
dev/alpha_console.cc:
    rather than accessing a charecter array of varying size depending on
    the access, lets actually do this properly.
dev/alpha_console.hh:
    get rid of now nolonger used consoleData
dev/disk_image.cc:
    We have to byte swap the data is some cases, added function to do that
dev/ethertap.cc:
    added preproc directive for mac os
