[PATCH v5 6/6] target/i386: Prohibit target specific KVM prototypes on user emulation

[Philippe Mathieu-Daudé]

None of these target-specific prototypes should be used
by user emulation. Remove their declaration there, so we
get a compile failure if ever used (instead of having to
deal with linker and its possible optimizations, such
dead code removal).
