Subject: configure: gate our use of GDB to 8.3.1 or above

The support of socket based debugging which we need for linux-user
testing is only really stable as of 8.3.1 so lets gate our use of GDB
on having a relatively modern version.

For direct testing you can just point to a locally compiled version of
gdb via configure, e.g.:

  ../../configure --gdb=$HOME/src/binutils-gdb.git/builds/all/install/bin/gdb
