RFR 8162999 Build give extraneous find warnings

[Gerald Thornbrugh]

Hi Everyone,

I would like to have the following change reviewed:

Bug: https://bugs.openjdk.java.net/browse/JDK-8162999

Webrev: http://cr.openjdk.java.net/~gthornbr/8162999/hotspot-webrev.01/ 
<http://cr.openjdk.java.net/%7Egthornbr/8162999/hotspot-webrev.01/>

It seems that my putback of JDK-8144278 created a merge issue where a 
previous
removed line from JDK-8132919 was placed back into JtregNative.gmk. This fix
removes the line again.  The presents of this line generates "No such 
file or directory"
errors messages during builds because the "hotspot/test/compiler/native" 
directory no
longer exists.

Before this change the "No such file or directory" error messages were 
seen in the
build logs and after the change the error messages where not placed into 
the log.

Please let me know if you have any questions or concerns.

Thanks,

Jerry
