+Subject: [PATCH] RISC-V: Install libstdc++/libcc1 etc to /lib64 instead of lib
+
+The problem is that if we are configured with `--disable-multilib`,
+  gcc -print-multi-os-directory
+outputs
+  .
+Thus the dest to install libraries is set to
+  /usr/lib/.
+While other platforms (x86-64, arm64) it will be
+  /usr/lib/../lib64
+Let's sync riscv64 with them
+
+Another problem is that
+  gcc -print-file-name=libzstd.so.1
+will output
+  /usr/lib64/lp64d/../lib64/libzstd.so.1
+which is also need to patched.
