Subject: [PATCH] tests: readlink* ("",... fails with EINVAL on newer kernels

readlink and readlinkat have typically failed with ENOENT for

the invalid, empty file name,  "".  However, with the advent

of linux-2.6.39, they fail with EINVAL.

* tests/test-areadlink.h (test_areadlink): Also accept EINVAL

when operating on the empty file name.

* tests/test-readlink.h (test_readlink): Likewise.
