    How to build tor for WD My Cloud EX2

WD My Cloud EX2 has an Marvell Armada-370 CPU (Marvell PJ4Bv7 Processor rev 1 (v7l)) with 512MB RAM.
This device uses 32-bit binaries with 64K page size. WD releases a cross-compilation environment as part of its "WD My Cloud EX2 GPL Source Code". Download it from WD support page (making sure it matches your firmware version) and follow the instructions in My_Cloud_EX2_Release_Notes_GPL_*.txt to setup the environment. I recommend using a Debian OS.
The following packages are required to use the cross-compilation environment: build-essential automake lib32z1
Building dependencies

Create missing directories
$ cd Open_Source_packages
$ source source.me
$ mkdir -p ../_xinstall/${PROJECT_NAME}/include ../_xinstall/${PROJECT_NAME}/lib

zlib
$ cd Open_Source_packages
$ source source.me
$ tar -xzvf zlib-1.2.3.tar.gz
$ cd zlib-1.2.3
$ ./xbuild.sh build
$ ./xbuild.sh install

libevent
$ cd Open_Source_packages
$ source source.me
$ tar -xzvf libevent-2.0.19-stable.tar.gz
$ cd libevent-2.0.19-stable
$ ./xbuild.sh build
$ ./xbuild.sh install
# can we use Open_Source_packages/libevent-2.0.19-stable/include instead?
$ make prefix=${PWD}/xinst install
$ mkdir -p ${XINC_DIR}/ && cp -rvf xinst/include/* ${XINC_DIR}/

openssl
$ cd Open_Source_packages
$ source source.me
$ tar -xzvf openssl-1.0.1m.tar.gz
$ cd openssl-1.0.1m
$ ./xbuild.sh build
$ ./xbuild.sh install

Building tor

$ cd Open_Source_packages
$ source source.me
$ curl https://dist.torproject.org/tor-0.2.7.6.tar.gz | tar -xzv
$ cd tor-0.2.7.6
$ curl https://gist.githubusercontent.com/juniorz/df4380ce852c799ea8f4/raw/xbuild.sh -O
$ chmod +x ./xbuild.sh
$ ./xbuild.sh build

Now copy src/or/tor to your device.
## Troubleshooting
If you see source: not found errors whle running ./xbuild.sh, edit the file and change the shebang to #!/bin/bash.
