You've only built qtbase. That means you have no Wayland client plugin.

The configure output is confusing. It says "yes" for a bunch of X11 things, but 
the "XCB" section only has "no":

Though none of them are about XCB itself, one would conclude it is enabled. 
The hint here that GLX wasn't enabled.

In any case, the XCB plugin didn't get built:

So this build has no XCB or Wayland, that's why you can't start applications. 
If you just want to test an application that starts and ends, you can use the 
offscreen one.
