So when compiling tons of source files with GCC one can use -j to use all available cores. But what about the linker? Is there a similar option to speed up linking or does GCC not support multi-threading? In some larger projects it can really take a while ... (... and I hate to wait!)

**Edit:** Thanks for pointing out that -j is a option for make and not gcc/g++. But this does not answer my question! I would like to know if gcc can use multi threading while *linking* a program!
