This may have something to do with the shell that "make" uses to run the 
commands. The compression command isn't seen as failed with dash for

It doesn't matter what shell is used to run xz_wrap.sh. The same problem 
exists with other compressors if they are missing.

commit ID, assuming that your clock is set correctly.
