Don't re-stat the BUILD file.

Previously readBUILD returned a newly created *build.File struct if it didn't find an existing BUILD file.  This meant that other functions that needed to know if there was an existing BUILD file had to stat the BUILD file to check if it existed.  Now, readBUILD returns a nil pointer if there isn't an existing BUILD, so the other functions can just check if the bld they're passed is nil.
