Sorry if this is a silly question, but how do I build `sim` support into
gdb?

I've tried running the following against the top-level configure script:

```
$ ../configure --enable-sim --enable-unit-tests --enable-maintainer-mode
$ make -j4
$ make -C gdb run
make: Entering directory '/home/daniel/dev/gdb/build/gdb'
[...]

(gdb) target sim
Undefined target command: "sim".  Try "help target".

```

Thanks,
Daniel
