tracetool: Add optional argument to specify dtrace probe names
Optional feature allowing a user to generate the probe list to match the name of the binary, in case they wish to install qemu under a different name than qemu-{system,user},<arch> Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Acked-by: Paolo Bonzini <pbonzini@redhat.com> Acked-by: Stefan Hajnoczi <stefaha@linux.vnet.ibm.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
