Usage:
        scons [target] [compile options]
Targets:
        pavo:                   Build VirtualMIPS for pavo emulation
        mknandflash:            Build mknandflash tool

Compile Options:
        jit:                    Set to 0 to compile VirtualMIPS *without* JIT support(pavo only). Default 1.
        lcd:                    Set to 0 to compile VirtualMIPS *without* LCD support(pavo only). Default 1.
        mhz:                    Set to 1 to test emulator's speed. Default 0.
        debug:                  Set to 1 to compile with -g. Default 0.
        o:                      Set optimization level.Default 3.
        cc:                     Set compiler.Default "gcc". You can set cc=gcc-3.4 to use gcc 3.4.
