fix issues with gdb 8.0
GDB 8.0 is compiled and linked with g++, but the linking of static targets (f.e. coldfire) fails, without declaring the functions in thread_db.h extern C. The compilation of gdb errors out with: thread-db.o: In function `thread_db_init()': thread-db.c:(.text+0x5b6): undefined reference to `td_ta_new(ps_prochandle*, td_thragent**)' thread-db.c:(.text+0x61e): undefined reference to `td_thr_get_info(td_thrhandle const*, td_thrinfo*)' thread-db.c:(.text+0x632): undefined reference to `td_symbol_list()' ..
