compiler A53 testcase error

Hi

I want to recompile A53 test case.

In MP030-BU-50000-r0p4-52rel2/cortexa53/logical/testbench/execution_tb/README,

I should install arm-none-eabi and aarch64-none-elf. It provide a manual way to download, config and make the toolchain.

But I met the error in Centos 7 OS.

Then I search the arm-none-eabi and aarch64-none-elf toolchain and found it in

https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads 

I downloaded and intsalled the newest gcc-arm-10.2-2020.11-x86_64-aarch64-none-elf and gcc-arm-10.2-2020.11-x86_64-arm-none-eabi.

When I use these toolchain, I meet the following err:

arm-none-eabi have the same problem.

How to fix it?
