[llvm-dev] Failed to build r273101

[Josh Kergan via llvm-dev]

I updated clang and llvm today and now I get an error when I run ninja.
I've been able to sucessfully build llvm and clang in the past, but now I
get the following error part way through the build.

cc: error: unrecognized argument to -fsanitize= option: ‘safe-stack’
cc: error: unrecognized command line option ‘-Wcovered-switch-default’
cc: error: unrecognized command line option ‘-fcolor-diagnostics’
cc: error: unrecognized command line option ‘-Wglobal-constructors’

I can't figure out why this is failing. I know that my cc is pointing at cc
(Ubuntu 5.3.1-14ubuntu2.1) 5.3.1 20160413. I can't figure out why is
started failing unless I need to specify a compiler other than cc for
cmake. I ran cmake as
cmake ../llvm -G "Sublime Text 2 - Ninja"
with no options and I deleted my CMakeCache after I first ran into this
error.
