Cross compile variable: TARGET_ARCH

Change HOST_ARCH to TARGET_ARCH that set build target architecture to avoid confusion
Fix readme: BUILD_HOST -> HOST_ARCH -> TARGET_ARCH

 ## Cross build for ARM
 
-Give `HOST_ARCH` variable to set the host architecture
+Give `TARGET_ARCH` variable to set the target architecture
 ```
-HOST_ARCH=armv7l make
-HOST_ARCH=armv7l make install
+TARGET_ARCH=armv7l make
+TARGET_ARCH=armv7l make install
 ```
 - supports only `armv7l` for now
 
 If you used `ROOTFS_DIR` to prepare in alternative folder,
 you should also give this to makefile.
 ```
-ROOTFS_DIR=/home/user/rootfs/arm-xenial BUILD_HOST=armv7l make
-ROOTFS_DIR=/home/user/rootfs/arm-xenial BUILD_HOST=armv7l make install
+ROOTFS_DIR=/home/user/rootfs/arm-xenial TARGET_ARCH=armv7l make
+ROOTFS_DIR=/home/user/rootfs/arm-xenial TARGET_ARCH=armv7l make install
 ```
