File tools/gyp/find_mac_gcc_version.py (right):

https://codereview.chromium.org/594243003/diff/1/tools/gyp/find_mac_gcc_versi...
tools/gyp/find_mac_gcc_version.py:30: return
'com.apple.compilers.llvm.clang.1_0'
Have you verified that this is really the right version of clang to request from
Xcode on v6.0?

I'm not sure how to "officially" – but

1) I can't find any reference to anything but com.apple.compilers.llvm.clang.1_0
on the web
2) This setting works fine – verified it builds as expected
