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.
