You are right, I do have arm cross-compiler installed.
But I though that 'b2' executable is a part of the package that I downloaded from BOOST site and this executable is built for x86 machine.
Running 'bootstrap.sh' copy this file to boost_root folder, am I wrong?

Yes, I run 'file' command', it prints a lot of warning like

but I don't understand why? I have downloaded Linux version of BOOST, it should work, shouldn't it?


Looks like you build b2 with oe cross-compiler toolchain.
Check your path environment variable. 
You're using wrong gcc/g++.
