[llvm] r307426 - [llvm-pdbutil] Fix build.

[David Blaikie via llvm-commits]

Looks like there should be a test for this in the LLVM tree, if that's
where the functionality is (with a committed PDB file or similar (if
there's a convenient YAML format or something, that's OK too), as
llvm-dwarfdump is tested)
