Install libgccjit into the compiler's sysroot when cg_gcc is enabled This PR installs the `libgccjit.so` library (which is essentially GCC) into the rustc sysroot (`stageN/lib` on Linux) when the GCC codegen backend is enabled. This allows using the GCC codegen backend "out of the box" with the resulting rustc. It would be nice to get rid of the `libgccjit.so.0` alias (https://rust-lang.zulipchat.com/#narrow/channel/131828-t-compiler/topic/Forcing.20unversioned.20dylib.20dependencies.20on.20Linux/with/534180740), but it's not blocking for this change. You can try running `x build std --set 'rust.codegen-backends=["llvm", "gcc"]'` and then compiling a hello world with `rustc +stage1 -Zcodegen-backend=gcc main.rs`. It is now also possible to build stage2 rustc when the GCC is configured to be the default codegen backend, without any further `LD_LIBRARY_PATH` hacks: `./x build compiler --stage 2 --set 'rust.codegen-backends=["gcc"]'`. After this change, it should be pretty simple to add a dist/rustup step for actually shipping cg_gcc to end users. CC ```@GuillaumeGomez``` r? ```@jieyouxu``` |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
