package/gcc: add OpenRisc patches for gcc version 11.1.0

At the moment of gcc 11.1.0 release the OpenRisc patches for -mcmodel=large
were still pending. They have been upstreamed yesterday as pointed in gcc
bugzilla[1]. So they will be part of gcc 11.3.0 or maybe before on 11.2.
2. Anyway at the moment if we try to build packages libgeos and protobuf
with OpenRisc gcc 11.1.0 it fails due to missing -mcmodel=large. So let's
add OpenRisc patches for it as done for all the previous versions.

Fixes:
still not appeared on autobuilers
