Two things can help there.  First, using the gold linker (if you are not 
already) and second, using Ninja.  The gold linker is substantially 
faster than the BFD linker.  And Ninja is smarter than make about 
parallelizing actions.  Cmake will happily generate the Ninja files for 
you with -GNinja.

Here are the results for my testing with all scripting enabled (Debian 
Buster)

seth@cpu1 (master) % time ninja
