You called, sir?

sgtm, but let abarth do the honors since I proposed such. These files do
actually affect the build, but I don't think they need a lot of OWNER guarding.

Hi Adam,
Eric proposed OWNERS=* for Source/build, but wanted to check with you that this
was a good idea.
How does it sound (and look) to you?

lgtm

Asked Barth in person.  He agrees.
