+
+Tentando compilar com a [seguinte instrução](https://www.olimex.com/forum/index.php?topic=496.0):
+
+    ./configure --build=arm --host=arm-linux-gnueabi
+    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi install prefix=$(pwd)/../destdir/
+
+## Criando um toolchain
+
+Primeiro, como `root`, vamos criar o chroot:
+
+    mkdir -p /var/chroot
+    debootstrap --verbose --arch armel --foreign wheezy /var/chroot/wheezy-armel http://ftp.debian.org/debian
+    cp /usr/bin/qemu-arm-static /var/chroot/wheezy-armel/usr/bin/
+    DEBIAN_FRONTEND=noninteractive DEBCONF_NONINTERACTIVE_SEEN=true \
+     LC_ALL=C LANGUAGE=C LANG=C chroot /var/chroot/wheezy-armel /debootstrap/debootstrap --second-stage
+
+Opcionalmente, dê permissão ao usuário comum:
+
+    chown -R vagrant. /var/chroot/wheezy-armel
+
+Como usuário comum:
+
+    cd /var/chroot/wheezy-armel
+    sb2-init -n -m emulate -c /usr/bin/qemu-arm wheezy-armel "arm-linux-gnueabi-gcc"
