    Hello,

    src:linux currently fails to build from source on sh4 due to the kernel
    image compression set to XZ (CONFIG_KERNEL_XZ=y). I tried setting the compression to GZIP (CONFIG_KERNEL_GZIP=y) in debian/config/sh4/config
    and disabling CONFIG_KERNEL_XZ with the following configuration:

    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?

    The issue is the xz process running out of memory during native kernel builds.

    Switching to gzip compression fixed the problem for me.
