[Qemu-devel] Build currently broken

[Luiz Capitulino <lcapitulino@redhat.com>]

 Hi Glauber,

 Very latest Anthony's tree doesn't build for me:

"""
cc1: warnings being treated as errors
/home/lcapitulino/src/rh-internal/qemu-qmp/kvm-all.c:158: error: ‘on_vcpu’ defined but not used
make[1]: *** [kvm-all.o] Error 1
make: *** [subdir-x86_64-softmmu] Error 2
"""

 The culprit seems to be 452e475196a3f8b6b96d16bbaca727ebc1278a97 . The
only user of on_vcpu() is protected by #ifdef KVM_CAP_SET_GUEST_DEBUG.

 The patch below fixes it for me.

    Fix broken build
    
    The only caller of on_vcpu() is protected by ifdef
    KVM_CAP_SET_GUEST_DEBUG, so protect on_vcpu() too otherwise QEMU
    may to build.
