Thanks, installed, and closing the bug.

Apparently, if you do:

  set debuginfo verbose 1

(probably in your ~/.gdbinit file or somesuch, so that it is set from
the beginning of the session), it is supposed to show you messages
about downloading.  But this is documented to be 1 by default, so
maybe you don't see it because gdb-mi.el "swallows" those messages?
Try from the shell prompt and see if you get any messages.  They are
supposed to begin with "Downloading".  I think the download will only
happen if you debug a program whose sources and/or debug info are not
available locally.
