Initial SCons-based build system. See www.scons.org.

'cd build; scons' will build ALPHA/m5.debug.
Use e.g. 'scons KERNEL/m5.opt' to build other binaries.
Read the comments in build/SConstruct for more details.

base/traceflags.py:
    Take basename of generated cc/hh files from command line instead
    of hardwiring them.  Lets us call the script from a different
    directory and still have the files end up in the right place
    (e.g. "base/traceflags.py base/traceflags").
