Log message:
    Add 'getthrds' declaration check in configure for AIX

    On newer versions of AIX (6.x and later), this function is actually
    declared in procinfo.h, thus causing a compilation warning when we
    re-declare it ourselves. This patch adds a configure check for that
    function allowing us to declare the function only if the declaration
    isn't already present in one of procinfo system header.

    gdb/ChangeLog:

    PR gdb/12116:
    * configure.ac: Add getthrds declaration check.
    * configure, config.in: Regenerate.
    * aix-thread.c (getthrds): Declare only if not already declared
    in procinfo.h.  More declaration out of get_signaled_thread to
    global scope.
