I manage to compile it for ARM and it seems to work fine on the Pandora
Modification on LinuxEnvironmentPlugin.java was simple :

I didn't need to do any modification on the native code. For the ant script, I don't like what I have done. It is more an hack than an elegant solution. I have modify the build.xml for Linux native by replacing the Linux x86 compilation by the ARM compilation (since I use an x86 to compile the ARM code) :
