Here is the promised follow-up patch.

If gdbserver is configured with
  --with-libthread-db=/path/to/libthread.db.{a,so}
then we link with the given library instead of libdl, and directly import
all the symbols from it.

Tested by configuring --with-libthread-db=/lib64/libthread_db.so.1 and
running 'make check RUNTESTFLAGS="--target_board native-gdbserver"'.
No regressions.
