簡単なプログラムのビルド・テスト
『Hello, World!』的な単純なコードをクロスコンパイルし、MA-E320 実機に転送して実行できるか試してみます。
ビルドします。
root@jessie:~# arm-linux-gnueabihf-gcc -O2 -Wall hello.c -o hello root@jessie:~# ls -l hello -rwxr-xr-x 1 root root 5416 Jan 8 14:30 hello root@jessie:~# file hello hello: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.32, BuildID[sha1]=388d399d609ced3b732f5e7c9e01ff90507754a1, not stripped
MA-E320 実機 に転送します。

MA-E320 で実行してみます。
root@plum:/tmp# ls -l hello -rwxr-xr-x 1 user1 user1 5416 Jan 8 14:27 hello root@plum:/tmp# ./hello Hello!
単純なプログラムはクロスコンパイラでビルドできました。
様々なライブラリをリンクするプログラムの場合、ライブラリのヘッダや共有ライブラリがリンク時に必要となるため、
このように簡単にはビルドできません。
もし難しいようであれば、実機でのセルフビルドもしくは 『PC上で root filesystem を変更する(QEMU使用)』 でchrootした環境でのビルドをお勧めします。
