RE: ninja install on ubuntu 16.04 for qemu-5.2.0 build

[<ckim@etri.re.kr>]

Hello Bin Meng and Philippe Mathieu-Daudé,

Thanks for the advice. I found apt-get update doesn't help,
But downloading ninja-build source from https://github.com/ninja-build/ninja and
Doing git checkout v1.7.0 and ./configure.py --bootstrap just builds ninja. (I just used v1.7)
Then I renamed /usr/bin/ninja and made a simbolic link to the newly built ninja as /usr/bin/ninja.
And found qemu-5.2.0 is built and runs ok with usual "configure --target-list=aarch64-softmmu" and make -j12 under build directory.
Thanks for the help!
Chan Kim
