Downgrade back to GDB 13.1 (#96)

i686-w64-mingw32 GDB 14.1 does not detect file changes. After rebuilds
it runs with stale debugging information and may put the target in an
invalid state. The user must either manually use the "file" command or
restart GDB in order to load changes. Mostly reverts f46b079.
