Parallel, Incremental Linking

The bottleneck for building on my multi-core machine is ld, which spends a considerable time consuming 100% of one core 
after ghc has finished generating object files. Moreover, GHC is largely IO bound, while ld is CPU bound; incremental 
linking would enable the two tasks to be performed in parallel (or am I being naive?)

Gold in an incremental and multi-threaded linker, but can only output ELF (not Windows). Is there a cross-platform 
solution suitable for GHC?
