Hi Athena,
Are you sure you want to build the full Linux cross compiler? You are aware that this is not the PULP-Newlib cross compiler, right? The error you mention should not occur when building the PULP-Newlib compiler. If it does, please post the command you used and the full console output as code snippet here.
If you really want to build the Linux cross compiler, you should use the upstream RISC-V GNU toolchain instead and post an issue there if you encounter the same problem.
