That seems a little convoluted, but I guess it's okay. That's one particular problem you might encounter if Clang and gcc for RISCV32 made different choices about enabling int128 by default. More generally, we want to ensure the C environment for both GCC and Clang is as close as possible, as any difference like this has the potential for causing difficult to debug differences in behaviour that confuse end users.
