GCC overrides automake's default rule for site.exp and creates its own
site.exp file, which includes (among other things):

        @echo "set target_triplet $(target)" >> ./site.tmp

It looks like it wouldn't really make any difference to GCC if
automake did that automatically, because we still need to create
site.exp ourselves for the other things we add in there.
