Zihao Yu de78d6ca0a x86-qemu,boot: fix strict aliasing bug by union 
* In gcc 12, by the strict-aliasing rule, gcc will consider elf32 and
  buf during calling copy_from_disk() point to different memory area.
  This will let gcc move the checking of EM_X86_64 ahead of
  copy_from_disk(), causing incorrectly parsing the x86_64 ELF header as
  x86_32.

README 

AbstractMachine is a minimal, modularized, and machine-independent 
abstraction layer of the computer hardware:

* physical memory and direct execution (The "Turing Machine");
* basic model for input and output devices (I/O Extension);
* interrupt/exception and processor context management (Context Extension);
* virtual memory and protection (Virtual Memory Extension);
* multiprocessing (Multiprocessing Extension).
