 Deprecated and removed features, and other changes affecting
 compatibility:
 
-* The big-endian ARC port (arceb-linux-gnu) has been removed.

 * abort is now async-signal-safe and its implementation makes longjmp
   from the SIGABRT handler always abort if set up with setjmp.  Use
   sigsetjmp to keep the old behavior, where the handler does not stop
   the process execution.
 
-* The nios2*-*-linux-gnu configurations are no longer supported.

 * dlopen and dlmopen no longer make the stack executable if a shared
