Package gcc-riscv64-linux-gnu depends on gcc-10-riscv64-linux-gnu which is too old for the new binutils. GCC 10 gives an error:

cc1: error: ‘-march=rv64imac_zicsr_zifencei’: unsupported ISA subset ‘z

The cross compiler package needs a respin to match the new binutils.

U-Boot, OpenSBI, Linux kernel require patches to build with the new binutils,e.g. https://lists.denx.de/pipermail/u-boot/2022-January/473499.html

we will not change the ISA for the upcoming 22.04 LTS release, but do the change not before the GCC 12 defaults change planned for 22.10.
