RFR: JDK-8161057 Solaris: deprecated/obsolete compiler flags should be removed

[Alan Burlison]

This removes redundant/incorrect compilation flags from the Solaris 
build environment.

https://bugs.openjdk.java.net/browse/JDK-8161057
http://cr.openjdk.java.net/~dcubed/for_alanbur/8161057-webrev/0-jdk9-hs-all/

I already have one commend from DanD:

> jdk/src/demo/share/jvmti/java_crw_demo/sample.makefile.txt
>     Copyright year updated to '2015' instead of '2016'.

I've already fixed that in my workspace but it's still present in the 
above webrev.

There were some JPRT test failures on OSX and Windows, as this changeset 
doesn't affect those platforms I believe they can be ignored.

There is some related cleanup in deploy, that will be covered by 
https://bugs.openjdk.java.net/browse/JDK-8161081, by removing the 
Solaris-related scripts.
