Build options are set via a build_options file in the

Browse source 
build directory instead of being inferred from the name
of the build directory.
Options are passed to C++ via config/*.hh files instead of
via the command line.  Build option flags are now always
defined to 0 or 1, so checks must use '#if' rather than
'#ifdef'.

SConscript:
    MySQL detection moved to SConstruct.
    Add config/*.hh files (via ConfigFile builder).

    Convert compile flags from def/undef to 0/1.
    Set via #include config/*.hh instead of command line.
arch/alpha/isa_desc:
    Convert compile flags from def/undef to 0/1.
    Set via #include config/*.hh instead of command line.
    Revamp fenv.h support... most of the ugliness is hidden
    in base/fenv.hh now.
base/mysql.hh:
    Fix typo in #ifndef guard.
build/SConstruct:
    Build options are set via a build_options file in the
    build directory instead of being inferred from the name
    of the build directory.
    Options are passed to C++ via config/*.hh files instead of
    via the command line.
python/SConscript:
    Generate m5_build_env directly from scons options
    instead of indirectly via CPPDEFINES.
python/m5/convert.py:
    Allow '0' and '1' for booleans.
    Rewrite toBool to use dict.
base/fenv.hh:
    Revamp <fenv.h> support to make it a compile option
    (so we can test w/o it even if it's present) and to
    make isa_desc cleaner.

# 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_SE or ALPHA_FS) 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
