Why does hello.c depend on grub_script.tab.h? AFAIK, only normal/lexer.c 
depends on grub_script.tab.h, and the dependency is automatically generated 
in my environment.

Isn't it normal in make??? When I play with make, I do "rm -f FILE; make 
FILE". I don't know anything else more elegant.

Well, the original idea I had was that it could be possible to implement 
grub-emu differently among architectures. Currently we only emulate PC. I 
cannot tell you if this is a good thing. As grub-emu does not use much in 
i386- or PC-specific code, this might be sufficient. If so, it is a good idea 
to share the same config in common.rmk.
