That's of course your choice. That said, 3.3 branch
commit traffic is light, and limited almost
exclusively to bugfix patches, so in all likelihood,

Why not let it copy it over (as it wants) during the
installation, then just delete the directories and
replace them with symlinks after gcc installs?

Assuming you don't plan on rebuilding gcc regularly,
it'd be a one time pain.
