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.
