On Debian, when you install binutils-gold, the system already updates the
alternatives to use that by default, so you don't need to do anything. I
don't know Arch well enough to know how it will behave. My Arch system
seems to have gold already, and ld is a hardlink (or a copy) to ld.bfd. In
this case, using the autoconf/cmake alternatives for selecting the
toolchain is recommended, or a symlink. (in this case it's ok because gold
IS a linker, while ccache is NOT gcc).

Yes, it should be just a matter of setting the appropriate toolchain
selection on autoconf/cmake. CC and CXX should just work.

What we normally do in LLVM docs is to never duplicate anything. So, if
there is a doc on buildslaves, you add a small paragraph saying to look at
the other document, and come back when you finished. It's better in the
long run than having to update lots of documents (in your case, three at
least) later when things change. ;)
