T16180: indicate that the stack isn't executable
Fix some tests (statically linked GHC vs libc)
When GHC is linked statically, the stdout C global variable that GHC uses isn't shared with the stdout C global variable used by loaded code.
As a consequence, the latter must be explicitly flushed because GHC won't flush it before exiting.
