With this change, I was able to build and test for aarch64 & riscv64 on x86-64 host as follow: Pre-requisite: - cross build toolchain for aarch64 ``` $ sudo apt install binutils-aarch64-linux-gnu gcc-aarch64-linux-gnu g++-aarch64-linux-gnu ``` - cross build toolchain for riscv64 ``` $ sudo apt install binutils-riscv64-linux-gnu gcc-riscv64-linux-gnu g++-riscv64-linux-gnu ``` - qemu user: ``` $ sudo apt install qemu qemu-user qemu-user-static ``` CMake invocation: ``` $ cmake ../runtimes -GNinja -DLLVM_ENABLE_RUNTIMES=libc -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DLIBC_TARGET_TRIPLE=<aarch64-linux-gnu/riscv64-linux-gnu> -DCMAKE_BUILD_TYPE=Release -DLIBC_TEST_COMPILE_OPTIONS_DEFAULT="-static" $ ninja libc $ ninja check-libc ```
