coreutils readlink test case port to Solaris

[Paul Eggert]

I installed this patch to work around a portability problem with CVS
coreutils and Solaris 8.

2004-07-27  Paul Eggert  <address@hidden>

        * tests/readlink/can-e: Don't assume that we can remove the
        working directory: this isn't possible under Solaris 8, say.
        * tests/readlink/can-f: Likewise.
        * tests/readlink/can-m: Likewise.
