   you can use export ac_cv_func_malloc_0_nonnull=yes to fix the error message
   
2. Fix for problem
   
Use ./configure --host=arm-linux --libdir=/usr/local/arm/4.2.2-eabi/lib --libdir=/usr/local/arm/4.2.2-eabi/usr/include to configure before make.
Must export the 4.2.2 usr/bin to $PATH. If you export the wrong version, you will get the illegal instrumention.
