Checklist

Describe your issue

In this example, the LoongArch compiler generates an R_LARCH_64_PCREL relocation for 1b - .. Unfortunately, older binutils linker does not support R_LARCH_64_PCREL and merely issue a warning instead of failing, leading to incorrect values in the linked executable.

fn main() {
    unsafe {
        core::arch::asm!(
            r#"
            1:
            nop
            .pushsection jump_table,  "awR"
            .balign 8
            .quad 1b - .
            .popsection
            "#
        );
    }
}

Update crosstool-ng for loongarch64
cebae30 
The current cross-compilation toolchain for the LoongArch64 target
consists of GCC 13.2.0, Binutils 2.40, and Glibc 2.36. However, Binutils
2.40 has known issues that in broken binaries without any error reports:

- rust-lang#121289
- cross-rs/cross#1538

This patch upgrades the cross-compilation toolchain for the LoongArch64 target
to resolve these issues.

- GCC: 13.2.0 -> 14.2.0
- Binutils: 2.40 -> 2.42

The new binaries remain compatible with the existing GCC 13.2.0/Glibc 2.36
distribution, and no issues have been identified.
