Revert 195090 "clang: Build in C++11 mode on linux & cros too."

Broke chromeos clang builder: Complains about libstdc++ 4.4, but is probably not
yet on precise.

Broke linux clang tests: unit_tests, content_unittests, components_unittests
all crash at startup with:
symbol lookup error: /b/build/slave/Linux_Clang__dbg_/build/src/out/Debug/lib/libcontent.so: undefined symbol: _ZN7content6Zygote26kMagicSandboxIPCDescriptorE

> clang: Build in C++11 mode on linux & cros too.

> But: Not yet on Android, not yet with asan, not yet with gcc.
> Only with clang, and only for linux & cros (in addition to mac,
> which has had this for a while).
