Sorry, there is something wrong about configure command. It is native build and configured by:

./configure --prefix=/usr --libdir=/usr/lib64 --sysconfdir=/etc --interp-prefix=/usr/qemu-%M --audio-drv-list=pa,alsa \
--with-confsuffix=/qemu --localstatedir=/var --disable-strip '--extra-ldflags=-Wl,--build-id -pie -Wl,-z,relro -Wl,-z,now' \
'--extra-cflags=-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches   -fPIE -DPIE' \
--enable-trace-backend=dtrace --enable-werror --disable-xen --disable-virtfs --enable-kvm --enable-curl --enable-libusb --disable-spice --disable-seccomp \
--enable-fdt --enable-docs --disable-sdl --disable-debug-tcg --disable-sparse --disable-brlapi --disable-bluez --disable-vde --disable-curses --enable-vnc \

After running "make check V=1", output shows:
