I never build on any of my laptops. I have a 8-thread VM running FreeBSD on a 
new-ish 6-core Broadwell. It builds world in 35-45 minutes and a new kernel in 
~3-5 minutes. I mount it over NFS and install to the laptops when I want to 
update. Obviously if you only have this Atom based machine then that's not a 
luxury you have. If that's the case I'd install llvm/clang from ports and skip 
both clangs from the build. I'd guess it's probably 70+% of the buildworld time 
 on my system and possibly > 80% on yours due to the large C++ memory usage.
