It’s weird to see this in a _linux file. Can you change it to
!defined(OS_OPENBSD)? Same elsewhere in this file.

It is even weirder to be including _linux files in openbsd builds, but not
defining OS_LINUX. I recognize this might be a significant undertaking, but
shouldn't we do it one way or the other, i.e. #define OS_LINUX for openbsd
builds and add #if !defined(OS_OPENBSD) where necessary (like we do for
chromeos), or create _openbsd versions of files where required (and don't
include _linux files)?
