I don't think I have any odd configure options, it doesn't look like any of 
that conditionally compiles, and I and my compiler seem to agree on a problem.  
I apologize if I'm being obtuse.

evas_common_scale_rgba_in_to_out_clip_smooth_mmx and 
evas_common_scale_rgba_in_to_out_clip_smooth_c match signatures with 
Evas_Command_Scale_In_To_Out_Clip_Cb: 11 parameters.

evas_common_scale_rgba_in_to_out_clip_smooth_neon gets called as if it were, 
and assigned to a variable of type Evas_Command_Scale_In_To_Out_Clip_Cb.

The only definition of evas_common_scale_rgba_in_to_out_clip_smooth_neon is 
here:

#ifdef BUILD_NEON
# undef SCALE_FUNC
# undef SCALE_USING_NEON
# define SCALE_USING_NEON
# define SCALE_FUNC evas_common_scale_rgba_in_to_out_clip_smooth_neon
# include "evas_scale_smooth_scaler.c"
# undef SCALE_USING_NEON
#endif

And evas_scale_smooth_scaler.c defines a function named SCALE_FUNC taking 16 
params.  Every non-neon instance declares SCALE_FUNC with a leading underscore, 
and wraps the call in a function that adapts the 11 param call to 16.
