This is for the *build* system (i.e. the system you are compiling on) so
its likely correct.

It then goes on to look at the target of "i586-none-linux-gnu" which
sounds wrong given you appear to have an armeb toolchain?

I suspect you need to target a big endian arm machine rather than
MACHINE=qemux86 which I suspect you're currently using?

Cheers,
