Okay, maybe its my fault. I'v solved this one simply:

first time I used a Qt for x64 system architect, 'cause my OS is x64 and I had previously described trouble; at last time I installed Qt for x86 system and set new kit config for my project, previous kit was saved, but didn't work again. Fortunately new kit configs work well.

The main cause of my trouble is using GNU ARM Toolchain for x86 system (I think so, but I'm not sure completely that I use x86 toolchain) - this one is the default build that simple user can install from official ppa-sources
