Thanks for the confirmation. I figured as much after taking a closer look at the toolchain and the libfakeroot built for the host.
Unfortunately my toolchain is not available in 64-bit but only 32-bit. Is there any way to tell ptxdist to build host tools as 32-bit like specifying CFLAGS=-m32 somewhere? I only found a way to set CFLAGS for the target in platformconfig. Or would this approach not solve my problem?

Thanks for your support.
