7141242: build-infra merge: Rename CPP->CXX and LINK->LD

The build-infra project is starting to move into jdk8. For the hotspot 
build to stay compatible with the changes, the naming of standard make 
variables, like CC and LD need to be standardized across the build. 
Currently hotspot names the C++ compiler CPP, which is traditionally the 
name of the preprocessor. The windows nmake files name the linker LINK. 
We would like to rename the C++ compiler to CXX and have the linker 
named LD everywhere.

Patch is tested with hsx/hotspot-rt. Testing with jdk7u is in progress.
