Greetings,

I disclaim any knowledge of C or Makefiles, but if I comment out the 
check for _FEATURES_H in config.h (as below), the vm builds fine on and 
for Aarch64 Linux.

/*
@#ifdef _FEATURES_H
@#error This file was included too late. Please make sure it is included 
earlier
@#endif
*/

I have no idea what this is checking for or who sets it.

The diagnostic output is:
