I am following the CLFS guide

, and I have setup my root .bashrc & settings, and my global GCC flags, and other customs things I like.
I have finished building the tool set, and now beginning the bootstrap stage3 build. I have browsed the "/tools" folder and noticed that the GCC $CHOST folder is named "
x86_64-unknown-linux-gnu" Can I rename this folder, to say "
x86_64-pc-linux-gnu"..? And set then global $CHOST variable in my ~/.bashrc ...?
Before I build this stage and possibly implement a package manager, I need to be certain that I can change my $CHOST variable, for future builds.
