RFR 8024046,Test sun/security/krb5/runNameEquals.sh failed on 7u45 Embedded linux-ppc*

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
