Subject: fixes so that M5 will compile under solaris

SConstruct:
    Add check to see if we need to include libsocket
src/arch/sparc/floatregfile.cc:
src/arch/sparc/intregfile.cc:
    use memset rather than bzero and include the appropriate headerfile
src/base/pollevent.cc:
    If we're compling under solaris we need sys/file.h
src/base/random.cc:
src/base/random.hh:
    solaris doesn't have random(), so use rint with the correct rounding mode
    if we're compiling on solaris
src/base/stats/flags.hh:
    u_int32_t??
src/base/time.hh:
    grab the timersub() define from freebsd since it doesn't exist in solaris
src/cpu/inst_seq.hh:
    we don't need to include stdint here
src/sim/byteswap.hh:
    the method to detect endianness on Solaris is a little more complex...
