Unfortunatly there isn't a prebuilt cross compiler for now, but there is a way.|
You have to install Oracle Jdk, netbeans for C and MinGw in Windows system and SSH on banana.
Then in nb select services tab, then right click on c/c++ build hosts and select add new host
It will connect trough SSH with Banana and deploy directly.
In some case Netbeans 8 don't find the remote gnu-compiler, in this case tray to install Jdk and Netbeans 7.0
Alternatly you can try to compile gcc for cross compiling with Cygwin but is long and horrible results.
