buildbot failure in LLVM on clang-x64-ninja-win7

[Fedorova, Vera via llvm-commits]

Sanjoy,

I have rebooted windows7-buildbot machine, deleted start directory and started full build.
These fails are still present :

Galina,

Can you please take a look to see if I'm setting the 'clobber' flag correctly in the two builds above?  Are there other ways I can force the bot do a "full" build?

Generally speaking, I don't think the second stage of a bootstrap bot should do an incremental build -- that is equivalent to running only a small percentage of the test suite. :)
