on the list of the GCC RV64I multi-libs (gcc/config/riscv/t-zephyr):

rv64i_zicsr_zifencei/lp64
rv64im_zicsr_zifencei/lp64
rv64im_zicsr_zifencei_zba_zbb_zbc_zbs/lp64
rv64imac_zicsr_zifencei/lp64
rv64imac_zicsr_zifencei_zba_zbb_zbc_zbs/lp64
rv64imafdc_zicsr_zifencei/lp64d
rv64imafd_zicsr_zifencei/lp64d
rv64imafc_zicsr_zifencei/lp64
rv64imafc_zicsr_zifencei_zba_zbb_zbc_zbs/lp64
