GDB HEAD on GNU/Hurd

[Thomas Schwinge <thomas at schwinge dot name>]

Hello!

This is only a friendly ;-) reminder to Pedro, so that he doesn't forget
about this issue in the lots of work he's doing.
<http://www.gnu.org/software/hurd/open_issues/gdb_head.html>; which I
bisected to his and Stan's multi-exec patch.

Pedro suggested a hack (and I confirmed that it works), it is ``#if 0''ed
out in gnu_create_inferior in the patch -- as I found another place where
the equivalent thing was already once planned to be done, next to our
funky pending_execs handling:

Pedro's concern was that this might be needed in other places as well.
