I'd expect one of: * List all six combinations in NEWS, with appropriate caveats about the state of kernel and glibc support for RV32 and soft-float, and a caveat about riscv32-*-linux-gnu in README (the latter caveat to be removed later once it's known to be working properly). * Remove the riscv32-*-linux-gnu README entry, and all the other RV32 support in the port.

Oh, sorry about that, I forgot about the README. I'm going to proceed for now with removing the rv32 support, if it's better to add the caveats then it'll be easy to back out the changes.
