Thanks, this tool has been of great help, nonetheless I think the problem is actually with my firmware (tomato-shibby)
I am not really a firmware compiler, for what I could understand the libc6 and kernel must be compatible, and the ones on that firmware does not play nice with Resilio
I have succesfully tried other libc6 versions from debian (thanks to your tool), but they just don't run on the device
It might need someone with more knowledge than me, or a different firmware; I suppose something more flexibe as openWRT will have no problems running resilio, just tomato is something more handy for day-to-day use
