I'm going to fix the misleading gnu-efi readme. So I have to replace not 
only the 64 bit variant, but efi-app-ia32, too, despite the fact that I 
don't want to use the 32 bit variant myself. For that goal I've read 
that bugzilla file again and again thoroughly, but it escapes me to what 
efi-app-ia32 is translated to. I can't dinf a "pei-ia32". Could you, 
please, tell me?

Kind regards
