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

[Sanjoy Das via llvm-commits]

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. :)
