or1k tool chain update to use GCC 9

[Sebastian Huber]

Hello,

the RSB uses now GCC 9 to for the or1k tool chain:

https://git.rtems.org/rtems-source-builder/commit/?id=8241563b6ec559fd562ec41147b04797a54dfe5f

I was able to build this RTEMS BSP with it and link the tests:

https://git.rtems.org/rtems/commit/?id=28bf4cae7878f4e47cc24c114fc9c5567247ecc1

Please test the tool chain and fix new warnings in the RTEMS build. It 
would be nice to have thread-local storage support for this port. The 
console driver should be converted to use the new Termios device driver API.
