[Bro] Worker in cluster with different processor architecture

I’ve got a new cluster being run with a manager on Intel hardware but the worker  on Raspberry Pi 2.  The Raspberry Pi was previously working in standalone mode successfully with Bro 2.4 compiled and installed. When I moved it into the manager/worker configuration, all went well with the installation except for the inevitable error due to the manager pushing an Intel executable over to the worker which it can’t recognize/run:

/usr/local/bro/bin/bro: 3: /usr/local/bro/bin/bro: Syntax error: Unterminated quoted string
/usr/local/bro/bin/bro: 1: /usr/local/bro/bin/bro: ELF: not found

I’ve scanned the online documentation and googled but haven’t yet found a workaround; I’d imagine there might be a way to have the master not overwrite the binaries and allow the native Raspberry Pi compiled binaries run? Or another approach I’m missing? Processor info follows the .sig. Thanks much.
