Steps to reproduce:
1. cd qemu-7.0.0 source code folder;
2. ./configure --target-list=riscv64-softmmu,riscv64-linux-user;
3. make -j$(nproc)
Additional information:
1. I downloaded the source code from https://download.qemu.org/qemu-7.0.0.tar.xz.
2. my compiling prerequisites:
sudo apt install autoconf automake autotools-dev curl libmpc-dev libmpfr-dev libgmp-dev \
              gawk build-essential bison flex texinfo gperf libtool patchutils bc ninja-build \
