Well, the easy part is just removing the deprecated configs from
gcc/config.gcc, but yes, cleanup in the port specific code could be done.

I CCed Jeff who is on the commitee to forward the maintainer proposal
though I guess this will not go forward as a first step.  Instead
you are probably expected to show activity on the port, for example
post the patch series to make ia64 use LRA, get write access to the
git repository and then be promoted maintainer.

It's good you started the copyright assignment process though
technically you can also contribute under the DCO.

As a first patch you might want to propose to un-deprecate the
ia64*-*-linux* triplets?

Thanks,
Richard.
