endian fixes and compiles on mac os x

Browse Source 
arch/alpha/alpha_linux_process.cc:
    add endian conversions for fstat functions
arch/alpha/alpha_tru64_process.cc:
    add endian conversions for various functions
sim/byteswap.hh:
    for some reason gcc on macos really wants long and unsigned long
    Why int32_t and uint32_t isn't sufficient I don't know.
sim/process.cc:
sim/syscall_emul.hh:
    endian fixes
