commit 45f8296e6965ff4e2ca855e995149add6352645d

    sim/m32r: Initialize "list" variable
    
    The variable "list" is only initialized when arg1 > 0 and when arg1 == 0,
    an uninitialized value is passed to translate_endian_h2t function.
    
    Although this behavior is harmless, this commit adds initialization to avoid
    a GCC warning ("-Wmaybe-uninitialized").
