Microcode: Show a useful warning when microcode bins are missing
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.
