I'm seeing the same thing here. Somehow some extra patches got slipped 
in between rc1 and rc2. The new patches for RISC-V are:

Samuel Holland <samuel.holland@xxxxxxxxxx>
    riscv: Save/restore envcfg CSR during CPU suspend

commit 88b55a586b87994a33e0285c9e8881485e9b77ea

Samuel Holland <samuel.holland@xxxxxxxxxx>
    riscv: Fix enabling cbo.zero when running in M-mode

commit 8c6e096cf527d65e693bfbf00aa6791149c58552

The first patch "riscv: Save/restore envcfg CSR during CPU suspend" 
causes the build failure.
