Major `cross' category overhaul. Clean up the shared Makefiles; move all
binutils stuff (except gas) to a shared, multiple-target binutils build;
reduce extract and compile times by being more specific with files and
targets; update to egcs 1.1.1 with a diffball from NetBSD's src/gnu/dist
tree; add 4.4BSD a.out archive support to binutils.
