Please review this small build fix. `configure` reports `default` instead of `musl` for targets ending in `linux-musleabi` or `linux-musleabihf`.
**Fix:** `PLATFORM_EXTRACT_VARS_FROM_LIBC` now uses `*linux*-musl*` instead of `*linux*-musl` to accept the ABI suffix. **Testing:** - `make test-make`: passed. - Added libc detection coverage to the existing Autoconf tests (`linux-musl`, `linux-musleabi`, `linux-musleabihf`, `linux-gnu`). - ARM32 musl cross-configure with an explicit `--openjdk-target=armv7l-unknown-linux-musleabihf`: reported `musl` after the fix. --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - 8387719: Building the JDK: running `bash configure` does not detect musl Changes: https://git.openjdk.org/jdk/pull/33300/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=33300&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8387719 Stats: 14 lines in 2 files changed: 12 ins; 0 del; 2 mod Patch: https://git.openjdk.org/jdk/pull/33300.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/33300/head:pull/33300 PR: https://git.openjdk.org/jdk/pull/33300
