build: Add missing 'riscv64' to configure --arch

The configure script didn't accept the riscv target arch and failed like below when I tried to cross-build: $ ./configure --arch=riscv64 --cross-compile=riscv64-linux-gnu- Error: 'riscv64' is not a supported architecture Also change the script to use 'case' statement to handle multiple architectures easily.
