bitcoin: ./contrib/guix/guix-build does not work on riscv64

Steps to reproduce:

# dpkg --print-architecture && HOSTS="arm64-apple-darwin" V=1 VERBOSE=1 MAX_JOBS=$(nproc) ./contrib/guix/guix-build 
riscv64
Found macOS SDK at '/bitcoin-core/depends/SDKs/Xcode-12.2-12B45b-extracted-SDK-with-libcxx-headers', using...
Checking that we can connect to the guix-daemon...

Hint: If this hangs, you may want to try turning your guix-daemon off and on
      again.
