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").

# Define Configurations
#
# The build system infers the build options from the subdirectory name
# that the simulator is built under. The subdirectory name must be of
# the form <CONFIG>[.<OPT>]*, where <CONFIG> is a base configuration
# (e.g., ALPHA or KERNEL) and OPT is an option (e.g., MYSQL). The
# following code defines the standard configurations and options.
# Additional local configurations and options are read from the file
# 'local_configs' if it exists.
#
# Each base configuration or option is defined in two steps: a
# function that takes an SCons build environment and modifies it
# appropriately for that config or option, and an entry in the
# 'configs_map' or 'options_map' dictionary that maps the directory
# name string to the function. (The directory names are all upper
# case, by convention.)
