gdb: Remove support for S+core

Browse source 
GCC removed support for score back in 2014 already.  Back then, we
basically agreed about removing it from GDB too, but it ended up being
forgotten.  See:

 https://sourceware.org/pipermail/gdb/2014-October/044643.html

Following through this time around.
