You will need to install some packages to your Debian/Ubuntu first:

sudo apt-get install bison libpixman-1-dev \
libxfont-dev libxkbfile-dev libpciaccess-dev \
xutils-dev xcb-proto python-xcbgen xsltproc \
x11proto-bigreqs-dev x11proto-composite-dev \
x11proto-core-dev x11proto-damage-dev \
x11proto-dmx-dev x11proto-dri2-dev x11proto-fixes-dev \
x11proto-fonts-dev x11proto-gl-dev \
x11proto-input-dev x11proto-kb-dev \
x11proto-print-dev x11proto-randr-dev \
x11proto-record-dev x11proto-render-dev \
x11proto-resource-dev x11proto-scrnsaver-dev \
x11proto-video-dev x11proto-xcmisc-dev \
x11proto-xext-dev x11proto-xf86bigfont-dev \
x11proto-xf86dga-dev x11proto-xf86dri-dev \
x11proto-xf86vidmode-dev x11proto-xinerama-dev \
libxmuu-dev libxt-dev libsm-dev libice-dev libudev-dev \
libxrender-dev libxrandr-dev curl autoconf automake libtool \
pkg-config libjpeg-dev libpng-dev

You will need both xcb-proto and python-xcbgen packages
to have version 1.10-1, you may download newer packages
from http://packages.ubuntu.com/ or https://www.debian.org/distrib/packages

Then run commands:

git clone git@github.com:pelya/commandergenius.git sdl-android
cd sdl-android
git submodule update --init --recursive project/jni/application/xserver-debian/xserver
rm project/jni/application/src
ln -s xserver-debian project/jni/application/src
./changeAppSettings.sh -a
android update project -p project
./build.sh

To build system image, download repo:

https://github.com/pelya/cuntubuntu

Install dependencies described in it's readme,
then go to directory img and launch script

./img-debug-wheezy-proot.sh

This will create Debian system image.

Upload resulting system image somewhere, and change download URL inside
AndroidAppSettings.cfg, then recompile .apk file.

New releases of Debian contain statically linked xkbcomp, xli and xhost executables
for XSDL, because NDK r10c toolchain for some reason builds xkbcomp, which crashes
on Toshiba AT-330 with Android 4.0.3. To create these executables, you will need
to create Debian x86 and armhf chroot installations, like this:

sudo apt-get install qemu-user-static

sudo qemu-debootstrap --arch=i386 --verbose \
        --components=main,universe,restricted,multiverse \
        --include=fakeroot,libc-bin,locales-all,build-essential,sudo \
        wheezy wheezy-x86 http://ftp.ua.debian.org/debian/

sudo qemu-debootstrap --arch=armhf --verbose \
        --components=main,universe,restricted,multiverse \
        --include=fakeroot,libc-bin,locales-all,build-essential,sudo \
        wheezy wheezy-armhf http://ftp.ua.debian.org/debian/

sudo qemu-debootstrap --arch=mipsel --verbose \
        --components=main,universe,restricted,multiverse \
        --include=fakeroot,libc-bin,locales-all,build-essential,sudo \
        wheezy wheezy-mipsel http://ftp.ua.debian.org/debian/

Put this into /etc/apt/sources.list in each chroot, then do sudo apt-get update:

deb http://http.debian.net/debian/ wheezy contrib main non-free
deb-src http://http.debian.net/debian/ wheezy main contrib

deb http://security.debian.org/ wheezy/updates contrib main non-free
deb-src http://security.debian.org/ wheezy/updates main contrib

deb http://http.debian.net/debian/ wheezy-updates contrib main non-free
deb-src http://http.debian.net/debian/ wheezy-updates main contrib

deb http://http.debian.net/debian/ wheezy-backports contrib main non-free
deb-src http://http.debian.net/debian/ wheezy-backports contrib main

Go to each of these chroots using chroot or schroot command, install all packages
mentioned in the previous section, then download and compile static executables:

wget http://cgit.freedesktop.org/xorg/app/xhost/snapshot/xhost-1.0.6.tar.gz
wget http://cgit.freedesktop.org/xorg/app/xkbcomp/snapshot/xkbcomp-1.2.4.tar.gz
apt-get source xli
wget https://github.com/kfish/xsel/archive/master.tar.gz

xhost:
./autogen.sh
env XHOST_LIBS="-static -lX11 -lxcb -lXau -lXdmcp -lXmuu -lpthread" ./configure
make V=1

xkbcomp:
./autogen.sh
env XKBCOMP_LIBS="-static -lxkbfile -lX11 -lxcb -lXau -lXdmcp -lXmuu -lpthread" ./configure
make V=1

xli:
cat debian/patches/series | while read F ; do patch -p1 < debian/patches/$F ; done
xmkmf
env EXTRA_LIBRARIES="-static -lxcb -lXau -lXdmcp -lXmuu -lpthread -ldl" make -e

xsel:
./autogen.sh
env LIBS="-static -lX11 -lxcb -lXau -lXdmcp -lXmuu -lpthread" ./configure ; make
make V=1
