Re: posix_spawn_file_actions_addclose on Solaris 11

[Bruno Haible]

While fixing this test failure on Solaris 11:
> 
>   test-posix_spawn_file_actions_addopen.c:49: assertion failed
>   FAIL: test-posix_spawn_file_actions_addopen

I introduced this configure message on a glibc system:

  checking whether posix_spawn_file_actions_addopen works... no                 
                                                                                
                       

This fixes it.
