I've been building xzcat for sh2 and sh4 in toybox? I just switched on 
CONFIG_KERNEL_XZ in my sh4 mkroot build, which barfed because xz wasn't 
in the $PATH on the build machine, but worked when I fixed that and the 
result booted under qemu-system-sh4.

What's the issue here? Missing build dependency, or something else?
