this patch fixes compilation of gdbserver on systems that don't have
thread_db.h. in that case we fall back to gdb's own copy
"gdb_thread_db.h", so the typedef of the td_thrhandle_t member is
available, which is accessed in other parts of the code without
checking whether thread_db.h is available.
this is by far the cleaner solution, removing the accesses to the
th member in other parts of the source would either litter it with
ifdefs or cripple the functionality.
