I have the same problem since I rebased an old branch onto last master. Before make ran fine, now I have systematically this error :

Makefile.common:189: recipe for target 'common-unused' failed
make: *** [common-unused] Error 1

Before I run the make, the file vendor/modules.txt is unchanged. But the make produced an error recipe for target 'common-unused' failed with a git diff of vendor/modules.txt showing some changes. But the changes are made by the make. If I discard changes, the same scenario occurs again and agin. I have Ubuntu 18.04.
