This adds support of rv64ilp32 toolchain available from Github repo
`ruyisdk/riscv-gnu-toolchain-rv64ilp32`. With this 32-bit nuttx can
be generated for RV64 devices.

LLVM supports (to various degrees) a number of experimental extensions.
All experimental extensions have experimental- as a prefix. There is
explicitly no compatibility promised between versions of the toolchain,
and regular users are strongly advised not to make use of experimental
extensions before they reach ratification.
Fix compile error:
riscv64-unknown-elf-clang: error: invalid arch name 'rv64gcv_zfh_zvfh', requires '-menable-experimental-extensions' for experimental extension 'zvfh'

Ubuntu stock toolchain `gcc-riscv64-unknown-elf` complains about
current CMake system (see issue#11573). This tries to fix it so
that both newer XPack and stock toolchains can be used with CMake.
