File Makefile of Package failed_cloudflared

# Minimal Makefile for building cloudflared in RPM build env.
# The original Makefile errored out when uname -m returned riscv64.
# This file adds minimal support for riscv64 by mapping it to GOARCH=riscv64
# and otherwise keeps a simple build rule so the RPM %build target can succeed.
