Log Message:
make: add detailed exit status to message for failed sub-commands

Several commands communicate via the exit status and not only
distinguish between zero and non-zero, so make this information
available to ease investigations.

The command "false" is not guaranteed to exit with a consistent status,
so use "(exit 13)" instead in the tests, to keep these tests portable
across different operating systems.  The exit status 127 is required for
a shell that cannot find a command, so keep that one.
