Can't answer that as I have no stocks in qt binary packages provided by Qt :) 

Anyway, up until Qt 5.6 the switch was -gtkstyle, with 5.7 the configure option 
was changed to -gtk. It will be on by default if the packages it depends on 
are installed. I guess noone checked that the plugin got built and packaged.

Try ./configure -v to see the results of the compile tests and check which 
packages you're missing (mostly -dev packages for Ubuntu/Debian)
