Hello, I've also had this issue. In my case I was trying to run make after installing the AUR package riscv-gnu-toolchain-bin (I never tried with the non-bin version). I could not find any information about this except that it might be related to the use of --multilib when building the package.

Anyway, I was able to compile and run xv6 by installing both parts of the toolchain from the community packages (riscv64-linux-gnu-gcc and riscv64-elf-gcc, both pull additional dependencies of the complete toolchain).

Hope this helps!
