r243470 decorates standard allocation functions like alloca

the attribute to aligned_alloc I had overlooked that the size

has led to __builtin_object_size() reporting the wrong size
for aligned_alloc-allocated objects and, consequently, to
checking functions like __memset_chk calling abort for buffer
bogus overflows.
The attached patch corrects this mistake by decorating the
function with the correct alloc_size attribute.
Ok.
I installed the patch on the trunk
