This is a follow up to #155722, adding library support for the target.

@rustbot rustbot added A-compiletest Area: The compiletest test runner A-LLVM Area: Code generation parts specific to LLVM. Both correctness bugs and optimization-related issues. A-run-make Area: port run-make Makefiles to rmake.rs A-test-infra-minicore Area: `minicore` test auxiliary and `//@ add-core-stubs` A-testsuite Area: The testsuite used to check the correctness of rustc S-waiting-on-author Status: This is awaiting some action (such as code changes or more information) from the author. T-bootstrap Relevant to the bootstrap subteam: Rust's build system (x.py and src/bootstrap) T-compiler Relevant to the compiler team, which will review and decide on the PR/issue. T-libs Relevant to the library team, which will review and decide on the PR/issue. labels May 13, 2026
