commit 5230fa047cf21da1ecd9f5ece337294ec8d0ec62

    validate: Add --build-only
    
    This will allow us to split up Harbormaster output for the build and
    test stages of validation.
    
    Test Plan: `./validate --build-only && ./validate --testsuite-only`
    
    Reviewers: thomie, hvr, austin

    (cherry picked from commit 4d2b15d5895ea10a64194bffe8c321e447e39683)
