Only qemu-system-FOO and qemu-storage-daemon provide QMP
monitors, therefore such declarations and definitions are
irrelevant for user-mode emulation.
Restricting the x86-specific commands to machine-target.json
pulls less QAPI-generated code into user-mode.
Add a stub to satisfy linking in user-mode:
/usr/bin/ld: libqemu-i386-linux-user.fa.p/target_i386_cpu.c.o: in function
`x86_cpu_get_feature_words':
target/i386/cpu.c:4643: undefined reference to
`visit_type_X86CPUFeatureWordInfoList'
collect2: error: ld returned 1 exit status
