+* Support for OpenRISC running on Linux has been added. This port requires
+ as least binutils 2.35, GCC 11, and Linux 5.4. Currently only soft-float
+ ABI is supported:

+ - or1k-linux-gnu

+ The OpenRISC ABI is 32-bit big-endian and uses 64-bit time (y2038 safe) and
+ 64-bit file offsets (LFS default).

Deprecated and removed features, and other changes affecting compatibility:
* On x86-64, the LD_PREFER_MAP_32BIT_EXEC environment variable support
