[Development] 32bit linux build of qt5.10.0 w/ webengine

[Michal Klocek]

Hi

It looks like the build can not proceed because of lack of working
ninja. Qt configure detects system ninja, and in case it does not work
builds internal one. In case for some reason this failed you can
still force the build to use internal ninja with configure option:

-no-feature-webengine-system-ninja
