Please review the fix at http://cr.openjdk.java.net/~weijun/8024046/webrev.00/
We used to believe every Solaris/Linux/Mac should have native GSS libs, but this is not always correct. However, we do notice that for every system with native GSS lib, it also has the krb5-config utility. Most are in /usr/bin, and Fedora in /usr/kerberos/bin. This is now used as an indicator of whether native GSS is installed.
*David*: Hopefully the test would pass on your ppc systems now. Thanks Max
