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.  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).

sim/process.hh:
    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.
