with libexpat. gdb processes built-in xml files even when
native debugging.

Subject: [PATCH] Fix build without libexpat
clear_threads_listing_context is used for thread listing methods other
than the xml based, but it's only defined when HAVE_LIBEXPAT is defined.

* remote.c (clear_threads_listing_context): Move higher up, out of
the HAVE_LIBEXPAT guard.
