When building the kernel with binutils 2.37 and GCC-11.1.0/GCC-11.2.0, the following error occurs: Assembler messages: Error: cannot find default versions of the ISA extension `zicsr' Error: cannot find default versions of the ISA extension `zifencei' The above error originated from this commit of binutils[0], which has been resolved and backported by GCC-12.1.0[1] and GCC-11.3.0[2]. So fix this by change the GCC version in CONFIG_TOOLCHAIN_NEEDS_OLD_ISA_SPEC to GCC-11.3.0.
