After chatting out of band, I hadn't appreciated GNU as assembles `call foo` to use R_RISCV_CALL_PLT these days (https://github.com/bminor/binutils-gdb/commit/70f35d72ef04cd23771875c1661c9975044a749c), so this is no longer a concern to me. The only broken situation would be using an old (pre-2.40, or >1y) binutils, but that's probably broken for other reasons already.
