These commands are filtered at build-time for i386/x86_64 binaries.
By using the recently introduced HMPCommand::arch_bitmask flag
we can filter them at runtime, making it possible to compile
hmp-commands[-info].hx files once.

Since these methods are used inconditionally within target/i386/,
define them in the same stub file.
