Add support of cross-compilation for linux-based targets.

Usage:
- Cross compile:
make debug.linux TOOLCHAIN=./build/configs/toolchain_linux_armv7l-el.cmake
- Build unittests
make unittests TOOLCHAIN=./build/configs/toolchain_linux_armv7l-el.cmake
- Run unittests on target board
./tools/runners/run-unittests-remote.sh <ip> <login> <pass>
- Run JavaScript test on target board
./tools/runners/run-tests-remote.sh debug.linux <ip> <login> <pass>
