Joe,

yes I followed the chroot method. Your remark implies that switching to
the boot method will work too since uname -m will yield the cpu type of
the target, right? The downside would be that building will take weeks
instead of hours (well, maybe just days ;-(.

What about the floating point issue? Would I also have to define
-msoft-float in order taking into account that the Vortex lacks the FPU?

Thanks for your helping hand so far!

Cheers,

Andreas
