GCC is free software.

Well, yes.  GCC was originally, as its name suggests, the compiler for
the GNU operating system, which these days mostly means GNU/Linux.
These days GCC is used for all manner of other things as well, but
it's not unreasonable to favour free software distributions on the
wiki.

In which case, all you have to do is go as far as the sceond
paragraph, which says:

 * Alternatively, after extracting the GCC source archive, simply run
   the ./contrib/download_prerequisites script in the GCC source
   directory. That will download the support libraries and create
   symlinks, causing them to be built automatically as part of the GCC
   build process.
