gold for linking

I just tried adding -fuse-ld=gold to the g++ linker flags, and my link time shrinks from 18 seconds to 6 seconds. And that's 
with single threaded linking. If I add "-Wl,--threads 
-Wl,--thread-count,8" it becomes 4 seconds. It doesn't seem to scale 
after 8 threads.

Any plans for adding official (perhaps optional) support for gold in the 
JDK build system?
