Changing the Prefix of a Yocto-Generated Toolchain

Hi everyone,

I would like to change my toolchain prefix. Currently, it is defined as "aarch64-poky-linux-"gcc/g++/ar...
Is it possible to change it to "nicolas-"gcc/g++/ar...?

By reading the documentation, I was under the impression that changing the TARGET_PREFIX variable would achieve this. However, I end up with a cryptic error message that ends like this:
