Subject: [PATCH] posix_spawn: fix stack setup on ia64 [BZ #21275]
The ia64-specific clone2 call expects the base of the stack mapping and
the stack size as sep arguments, not an initial stack value as on other
stack-grows-down architectures. Reuse the stack-grows-up macro so we
pass in the right stack base.
Reported-by: Matt Turner <[email protected]>

(cherry picked from commit 7043946c7921c0e3850dd2b3d948336624bb0f62)
