It's painful and not something I'm going to do again.  Last time I did
so I managed to break binutils-gdb.

The process goes like this:
1) Some ports have been removed from gcc but not binutils-gdb, so
firstly revert those patches to the top-level on the gcc side.

2) Copy over the gcc configury and makefiles.

3) Reapply binutils patches that haven't been applied to gcc, either
because the people making the patches didn't care enough to submit
them to gcc, or because the gcc maintainers didn't care enough to ack
those patches.

This was the list I used last time.  Very likely it needs updating.
