[PATCH] gdb: Add i386-gnu-tdep to the list of objects for x86_64-*-gnu*

[PATCH] gdb: Add i386-gnu-tdep to the list of objects for x86_64-*-gnu*

[Sergio Durigan Junior]

When starting GDB on Hurd amd64, one will currently see the following
warning:

  # gdb -q
  gdb: warning: A handler for the OS ABI "GNU/Hurd" is not built into this configuration
  of GDB.  Attempting to continue with the default i386 settings.
  (gdb)

This happens because, in gdb/configure.tgt, the "x86_64-*-gnu*" target
is not pulling in the i386-gnu-tdep.o object, which means that only
64-bit debugging is currently supported.

The fix here is to add i386-gnu-tdep.o to the gdb_target_obs for Hurd
amd64.

What do you think of also pushing this change to the gdb-17-branch?

That'd be great, and it'd allow me to drop one patch from the Debian
package.

BTW,
https://inbox.sourceware.org/gdb-patches/87tt1dudhc.fsf@sergiodj.net/T/#t
also contains a patch needed for gdb-17-branch.

Thanks!

Let's backport, then. I think this one is pretty straightforward.

Agreed.  I've set the target milestone of the bug to 17.1 and pushed the
commit to the gdb-17-branch.

Thanks!
