Point release to fix OpenRISC

[Olof Kindgren]

Hi people,

I'm part of the OpenRISC community and was very happy to see the
OpenRISC support being added for newlib 2.2.0. Unfortunately a few
patches came in after the release, with the result that the OpenRISC
target in newlib 2.2.0 doesn't work at all.

Would there be any interest in releasing a 2.2.1 now that all
OpenRISC-related patches are applied? I haven't found any release
policies, but noticed that new minor versions are released
approximately once a year.

Best Regards,
Olof
