jdk8 makefile changes

[David Holmes]

Hi Omair,

The static vs dynamic link check that you see is only in place for the 
JDK libraries not hotspot. For hotspot (which has not been modified as 
part of the build-infra project) you still need to pass STATIC_CXX=false 
as a make variable on the make invocation.
