Alexandru Ardelean 079d57b0f2 gdb: disable simulator ; it's broken on ppc
Error is:

```

Seems others are running into this as well.
The problem seems to be that some code may be built
as C++ and not C, which may explain the linker error.

On this thread reply:
   https://sourceware.org/ml/gdb/2016-11/msg00045.html
it mentions that the simulator should not call GDB's
"error" function directly, but rather use the "host_callback"
struct.

I have no idea about the use of the GDB simulator within
the OpenWrt/LEDE community.

So, I took the easier route, which is to disable the simulator.
(Also suggested here: https://sourceware.org/ml/gdb/2016-11/msg00047.html )

If needed, I can make an effort to fix the simulator for PPC.
