Coming soon: JDK 9 Platform/Compiler upgrades at Oracle

[Bradford Wetmore]

Sorry for the wide distribution, but there is an important followup to a 
message from June.  If you are not building on Solaris, you can skip this.

A recent change to a hotspot CC invocation now requires the new Solaris 
Studio 12.3 compilers be found in your PATH/ when running "configure", 
or else the hotspot build will fail:

Linking vm...
...
/java/devtools/i586/SUNWspro/SS12u3/bin/CC -m64 ... -Wl,-z,defs \
     -o libjvm.so ...lots of .so files and libraries...

date:        Thu Sep 25 10:01:53 2014 +0200
summary:     8055141: Catch linker errors earlier in the JVM build by 
not allowing unresolved externals

+  LFLAGS_VM                += -Wl,-z,defs

For Oracle folks, the usual tree has the new compilers under the SS12u3 
directory.

WARNING, there is currently *no check* for this requirement in configure.

I know at least one other person who has run into this, so hopefully 
this saves others some time.
