Because the binary repo is disabled by default, we get frequent
questions about why the build failed, relating to microcode in the
binary repository.
- Show an error saying that the file is missing instead of the typical
make error of no rule to build the file.
- Show a note encouraging users to try enabling the binary repo if it's
not enabled.
