Integrated GCC-2.6.1 -> GCC-2.6.2 changes.

Notice that the libgcc DOESN'T change number, because there are no
changes.

Also now the gnu2bmake stuff is synchronized again.

I commit this so that others can test too.

You might want to postpone any "make worlds" until tomorrow, to
avoid any problems I didn't see in the first pass.

Thanks to Bruce for rounding up our changes to gcc.
