Fixed the first style issue by removing target64() as it is not needed:

WARNING: externs should be avoided in .c files
#68: FILE: arch/x86/cpu/i386/cpu.c:524:
+       void target64(void);

WARNING: externs should be avoided in .c files
#83: FILE: arch/x86/cpu/i386/cpu.c:539:
+       extern char gdt64[];

Leave the 2nd one in the codes, and

applied to u-boot-x86, thanks!
