Unfortunately, this is not very useful, because this patch series is no
longer there. I just did a build like this:

BR2_riscv=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_INIT_NONE=y
BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_HTOP=y
# BR2_TARGET_ROOTFS_TAR is not set

it uses gcc 13.x, on RISC-V 64-bit and it builds fine.

So for issues that have not been reported in the autobuilders, what is
good is to provide a defconfig that allows to reproduce the problem, so
that we can reproduce it again in the future.

Could you look into this, and submit a v2 if relevant?

Thanks!

Thomas
