Building each release tool natively needs a GitHub runner per platform. Cross-compiling on a Linux x86_64 runner instead lets us add platforms that lack GitHub runners, e.g. other Linux CPUs, as suggested in bazel-contrib#4217's review. The Linux aarch64 job now runs on an x86_64 runner and cross-compiles for musl (aarch64-unknown-linux-musl) instead of glibc. Rust links musl statically with its bundled rust-lld, so the build needs just a dev-only Rust toolchain, not a C cross toolchain. macOS and Windows files need those OSes' SDKs, so their jobs still build natively, and Linux x86_64 keeps its static glibc build. build.sh now takes the job's target triple and builds for the matching platform in dev/platforms, so the workflow skips older refs without it. release_files still picks the release flags, now from the platform's OS and libc. verify.sh also checks the CPU of Linux files, since one is now cross-compiled. Work towards bazel-contrib#4216

Building each release tool natively needs a GitHub runner per

The Linux aarch64 job now runs on an x86_64 runner and cross-compiles

files need those OSes' SDKs, so their jobs still build natively, and
Linux x86_64 keeps its static glibc build.
build.sh now takes the job's target triple and builds for the
matching platform in dev/platforms, so the workflow skips older refs
without it. release_files still picks the release flags, now from
