[PATCH 0/3] A few fixes to OpenBSD's native target

[John Baldwin <jhb@FreeBSD.org>]

The first patch is an alternative fix for the issue Simon ran into
with OpenBSD trying to use the x86 debug registers when it doesn't
support their use by a debugger.

The second patch pacifies a compiler warning due to the lack of debug
register support.

The third patch fixes an issue where an existing process tripped an
assertion where find_inferior_pid was called with a pid of 0
(unfortunately stack traces don't work for OpenBSD core dumps, so I
couldn't easily tell where hte failure was).  However, the use of
inferior_ptid is not correct anymore in ::wait methods and fixing that
alone allows a process to exit cleanly without error.

This is enough to get a single threaded program to run and exit
cleanly (which is all I tested).  There are likely other issues in the
OpenBSD target, but this at least gets it working for the simple case
again.

John Baldwin (3):
  Don't compile x86 debug register support on OpenBSD.
  x86-bsd-nat: Only define gdb_ptrace when using debug registers.
  obsd-nat: Various fixes to obsd_nat_target::wait.
