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.
