GCC-12.1.0 bumped the default ISA spec to the newer 20191213 version,
which moves some instructions from the I extension to the Zicsr and
Zifencei extensions. This requires explicitly specifying Zicsr and
Zifencei when GCC >= 12.1.0. To make life easier, and avoid forcing
toolchains that default to a newer ISA spec to version 2.2. For
clang < 17 or GCC < 11.3.0, for which this is not possible or need
special treatment.
