I did a quick test a while back, not sure which versions I tested, but 
FWIW:

Linking Qt5Widgets:
   gnu ld: 5 seconds
   gold: 3 seconds
   gold --threads: 1.6 seconds # Requires compilation with 
--enable-threads
   llvm ldd: 0.7 seconds # Threads enabled by default in newer llvm

ldd was the fastest
