[cfe-dev] Building clang

[denis gantsev via cfe-dev]

Hi
Thanks to everyone, indeed, using "-DLLVM_PARALLEL_LINK_JOBS=1
-DLLVM_USE_LINKER=gold -DLLVM_TARGETS_TO_BUILD=X86", actually worked!
P.S I had to turn off swap completely, because I prefer process being
killed than my laptop being unusable

Thanks again
Regards
Denis
