This part leads to a link error on all platforms that don't have readlinkat().
To reproduce:

1. Create a testdir for module 'areadlinkat'.
$ ./gnulib-tool --create-testdir --dir=/tmp/testdir --with-tests areadlinkat

2. Copy it to a platform such as MacOS X 10.5 and compile it:

$ ./configure
$ make
...
gcc  -g -O2   -o test-areadlinkat test-areadlinkat.o ../gllib/libgnu.a  
Undefined symbols:
  "_areadlink", referenced from:
      _areadlinkat in libgnu.a(areadlinkat.o)
      _areadlinkat in libgnu.a(areadlinkat.o)
      _areadlinkat in libgnu.a(areadlinkat.o)
ld: symbol(s) not found
collect2: ld returned 1 exit status
make[4]: *** [test-areadlinkat] Error 1


This fixes it:
