Ok, I am new to this. what do I provide to --target? --target=FreeBSD ? 
And what libraries will i need to copy from the fBSD system? What is the 
purpose of set sysroot in this case? Where do I use it? Inside gdb? On 
the shell?

Thanks for the reply, I just need some more info to go on. I've never 
tried a cross system core back trace, so this is all new to me.
