Patch rules_rust 0.68.1 to support riscv64 as a host architecture: - Add riscv64gc to supported linux architectures in triple.bzl - Add riscv64gc-unknown-linux-gnu to SUPPORTED_PLATFORM_TRIPLES in crate_universe for generated BUILD files - Register riscv64gc Rust toolchain with Rust 1.86.0
toolchains_llvm 1.6.0 does not support riscv64 as a host architecture. Patch three files to add linux-riscv64: - toolchain/internal/common.bzl: add (linux, riscv64) to SUPPORTED_TARGETS - toolchain/internal/configure.bzl: add riscv64-unknown-linux-gnu target system name mapping - toolchain/cc_toolchain_config.bzl: add linux-riscv64 toolchain config entry mirroring linux-aarch64 Also configure llvm.MODULE.bazel to use the system-installed clang-19 at /usr/lib/llvm-19 as the toolchain root for riscv64, since no prebuilt LLVM distribution exists for riscv64 Linux host.
_is_hermetic_or_exists needs to strip the %workspace% prefix before checking path existence, so include dirs like lib64/ or arch-specific c++/v1 are filtered out when they don't exist on the host. This is a generic bug affecting any toolchain_root usage with absolute paths.
Patch aspect_bazel_lib to add linux_riscv64 platform support for the expand_template toolchain. Download prebuilt expand_template binary from GitHub releases instead of requiring a local host build.
Add riscv64 to openssl build using a patched overlay tarball with constants-linux-riscv64.bzl. Enable perlasm assembly generation for riscv64 (same approach as x86_64/aarch64) using a relocatable perl toolchain. Post-process perlasm output to fix non-PIC JAL instructions for shared library linking.
