A revert of this CL (patchset #1 id:1) has been created in
https://codereview.chromium.org/2520453002/ by thakis@chromium.org.

The reason for reverting is: Makes every link on Mac warn

clang: warning: libLTO.dylib relative to clang installed dir not found; using
'ld' default search path instead [-Wliblto]

Probably due to https://reviews.llvm.org/D25932. We need to talk to Mehdi and
come up with a plan. Also, it's lame that that warning isn't affected by
-Werror, else the bots would've caught this..
