[binutils-gdb] Make gdb/linux-nat.c consider a waitstatus pending on the infrun side


https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=72b049d38ce85c51fc9f97ee64b00a47be5ebe94

commit 72b049d38ce85c51fc9f97ee64b00a47be5ebe94
Author: Pedro Alves <palves@redhat.com>
Date:   Tue May 24 14:47:57 2016 +0100

    Make gdb/linux-nat.c consider a waitstatus pending on the infrun side
    
    Working on the fix for gdb/19828, I saw
    gdb.threads/attach-many-short-lived-threads.exp fail once in an
    unusual way.  Unfortunately I didn't keep debug logs, but it's an
    issue similar to what's been fixed in remote.c a while ago --
    linux-nat.c was not fetching the pending status from the right place.
    
    gdb/ChangeLog:
    2016-05-24  Pedro Alves  <palves@redhat.com>
    
    	PR gdb/19828
    	* linux-nat.c (get_pending_status): If the thread reported the
    	event to the core and it's pending, use the pending status signal
    	number.
