commit 6e5af7486d432c54173bbba304001bdaa054a87b

    Initialize fpu_type to SSE2 instead of AUTO.
    
    This shows up when creating executables.  Executables don't have the
    magic number in the core file to indicate whether the core suports
    sse2 or x87, so the fpu_type is never set to the actual type, and
    fpu_mode is set to the value of fpu_type.  But there are asserts in
    the C code to check that fpu_mode is SSE2 since we have dropped
    support for x87.
    
    One case where this happens is building maxima with a cmucl executable
    on darwin.  An assert triggers preventing maxima from running.  This
    change fixes that.
