    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:
    it mentions that the simulator should not call GDB's
    "error" function directly, but rather use the "host_callback"
    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.
