How to use custom gcc to build static library

help
1

I want to compile rust programs using a custom GCC toolchain
I try to add a new target. But it doesn't seem to be working

An error is returned when compiled

error: data-layout for target `test-15916131297364407962`, `e-m:e-p:32:32-n32-S32`, differs from LLVM target's `riscv32-none-elf-gcc` default layout, `e-m:e-p:32:32-i64:64-n32-S128`

Here is the target json

    "arch": "riscv32",
    "cpu": "generic-rv32",
    "crt-objects-fallback": "false",
    "data-layout": "e-m:e-p:32:32-n32-S32",

        ]
    }
