delayed syncing of Xcode 4.4 Command Line Tools on Lion with ML

[Jack Howarth]

   Did anyone else notice that the initial release of Xcode 4.4 on Lion seemed to install an
older version of the Command Line Tools on Lion than on Mountain Lion? Also, when the Xcode
4.4.1 update was released it didn't initially seem to have a Command Line Tools update for
Lion (at least through the Preferences panel in Xcode). I was happily surprised today to 
find that a Command Line Tools update appeared in the preferences panel of Xcode 4.4.1
on Lion and that this update brings clang and the linker to the same versions as on ML.
This fixes a number of linker bugs such as radr://10466868, "-undefined dynamic_lookup linker bug"
and provides a much more satisfying endpoint for Xcode on Lion than the initial Xcode 4.4
release.
