So simply filtering out the warning like:
Index: gdbserver_tests/filter_stderr

+    -e '/pid is optional if only one valgrind process is running/d' \
+    -e '/warning: remote target does not support file transfer, attempting to access files from local filesystem./d'

Makes all gdbserver_tests PASS again, except one gdbserver_tests/hgtls.
But that seems an unrelated issue. Shall we just go with a filter, or do
you want to look into supporting file transfers in vgdb first?

Thanks,
