Added missing Hotspot make targets for 'optimized' build.

Hotspot VM has 'optimized' build version which is used to collect 
statistic and for stress testing. A corresponding source code is guarded 
by #ifndef PRODUCT and by 'notproduct' flags.
Switching to full forest build for Hotspot development requires to build 
all JVM targets from top repository. Unfortunately 
'--with-debug-level=optimized' build is broken on OSX because of missing 
targets in Hotspot makefiles.

Tested the build on OSX, Linux, Solaris (I don't have Windows).

Thanks,
Vladimir
