A very fast linker to replace gcc's ld

[Asman01]

Today I've found a good alternative to slow gcc's linker: gold. 
Written by  Google in C++ it's a linker writen for large code 
bases with C++ in mind. The author claims it's about 5 times fast 
than gcc's one. It does support ELF only and UNIX-like symtem I 
think it's enough to dmd on linux or am I missing something? I 
believe it can reduce a lot dmd's compilation speed on these 
system. It's under same GPL as gcc's ld. I wonder if we can use 
it to make dmd still fastest. :)
It seems same case as Facebook needed a new C++ preprocessor for 
its large code base.
