  "message": "Add //cc/libc config settings for C standard libraries (#792)\n\nAdds a new `//cc/libc` package with `config_setting`s for common C standard libraries, fed by a new `libc_flag` rule that exposes the current CC toolchain\u0027s `target_libc` value to `select()`. This mirrors the existing `//cc/compiler` package for compilers.\n\nCovered libcs: `glibc`, `musl`, `uclibc`, `bionic`, `macosx` (Apple\u0027s libSystem, using the historical value set by toolchains for all Apple platforms), `freebsd`, `netbsd`, `openbsd`, `msvcrt`, `ucrt`, `msys`, `newlib`, `picolibc`, `llvm-libc`, and `wasi-libc`. Toolchains not shipped with Bazel are encouraged to use the same canonical names.\n\nSince Bazel documents `target_libc` as \"the libc version string (e.g. `glibc-2.2.2`)\", `libc_flag` strips a version suffix (everything from the first `-` followed by a digit) before matching, so versioned values still match their family\u0027s setting while names like `wasi-libc` and `llvm-libc` are preserved.\n\nThe following changes make the new constraints usable:\n* the auto-configured Unix toolchain detects the default libc via preprocessor macros and `-dumpmachine`\n* the `target_libc` values emitted by the bundled Windows and BSD toolchain configs are changed to the correct values\n* rule-based `cc_toolchain`s can declare their `target_libc` or fall back to a reasonable default\n\nCloses #792\n\nCOPYBARA_INTEGRATE_REVIEW\u003dhttps://github.com/bazelbuild/rules_cc/pull/792 from fmeum:libc-settings 7215a9ced75b2d01816d25b87e76c8387b0eee34\nPiperOrigin-RevId: 970542238\nChange-Id: Id569a70de73fc51ca8c69ca74169b8ba44cdc1bf\n",
