[cfe-dev] Clang Build error

[Nemanja Ivanovic via cfe-dev]

I'm not sure if using ninja is an option, but if you're using it, you can
also configure cmake with -DLLVM_PARALLEL_LINK_JOBS=1 to keep the RAM
consumption down during linking. Although if you're running out of RAM on a
single link job, this of course won't help.
