tests/run-make/link-eh-frame-terminator/rmake.rs recipe fails during test run for link-eh-frame-terminator on riscv64 target in x86 QEMU environment

[CaiWeiran]

Description:
I am encountering an issue while running the official CI tests on a riscv64gc-unknown-linux-gnu target in an x86_64 QEMU environment. The test [run-make] tests/run-make/link-eh-frame-terminator fails during the linking stage with the error: Relocations in generic ELF (EM: 243) and error adding symbols: file in wrong format. The test fails when linking with cc.

Steps to Reproduce:

1. Run the command: python3 ./x.py --stage 2 test --host='' --target riscv64gc-unknown-linux-gnu tests/run-make/link-eh-frame-terminator/rmake.rs in a QEMU environment with an x86_64 host and a riscv64gc-unknown-linux-gnu target.
2. Observe the error message during the test execution.

Error Output:

``` [TIMING] core::build_steps::tool::Rustdoc { compiler: Compiler { stage: 2, host: x86_64-unknown-linux-gnu, forced_compiler: false } } -- 0.058 Testing stage2 compiletest suite=run-make mode=run-make (x86_64-unknown-linux-gnu -> riscv64gc-unknown-linux-gnu)

```

Expected Behavior:
The test should pass successfully, and the linker should handle the target architecture properly.

Environment:

• Rust version: 1.88.0 (Lastet)
• Target architecture: riscv64gc-unknown-linux-gnu
• Host architecture: x86_64-unknown-linux-gnu (QEMU)
• Operating System: Ubuntu 20.04

Additional Information:

• When running the same test in a native riscv64 environment (not under QEMU), the test passes successfully without any errors.
• This issue specifically occurs in the emulated QEMU environment when linking with riscv64-linux-gnu-gcc.
