[PATCH 0/4] Handle null inferiors in target::read_description

[John Baldwin <jhb@FreeBSD.org>]

This is a set of changes split out from my larger XSAVE review that
will hopefully be easier to review as a smaller chunk.  Compared to
the version of these patches posted previously I have added extra
details to the log messages for patches 1 and 2 and added two new
patches.  Namely, patch 4 now includes a test for this case (and patch
3 is some refactoring in preparation for patch 4).

John Baldwin (4):
  *-fbsd-nat: Handle null inferior in read_description.
  *-linux-nat: Handle null inferior in read_description.
  Add a have_native_target helper function for use with require.
  Test that native targets can read a tdesc without a process attached.
