That’s not the *package* name; this is the *variable* name.

We decided to hide “gcc” because over the past few years people would
often install it when they wanted GCC — a reasonable deduction to make.
But our “gcc” package on its own does not give you a working GCC – the
“gcc-toolchain” package does.  So by hiding the “gcc” package it is much
less likely that someone looking for GCC will end up with a broken package.
