In case it helps, on my 10.11.6 system, those two commands yield: $ ls -la /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs total 4 drwxr-xr-x 4 root wheel 136 Dec 19 2016 . drwxr-xr-x 5 root wheel 170 Dec 19 2016 .. drwxr-xr-x 5 root wheel 170 Dec 19 2016 MacOSX.sdk lrwxr-xr-x 1 root wheel 10 Nov 2 2016 MacOSX10.12.sdk -> MacOSX.sdk $ ls -la /Library/Developer/CommandLineTools/SDK* total 4 drwxr-xr-x 4 root wheel 136 Dec 13 2016 . drwxr-xr-x 5 root admin 170 Dec 13 2016 .. drwxr-xr-x 5 root wheel 170 Sep 17 2017 MacOSX.sdk lrwxr-xr-x 1 root wheel 10 Dec 13 2016 MacOSX10.12.sdk -> MacOSX.sdk I've no memory of how this came about.
