BUILD OK is shown twice when in a real project situation

[mmitch]

this does not happen with the example projects in cobol-build, but with every real world scenario where cobol-build is used in a real project (see ToDoListe or cobol-anagram-kata repos for example).

Looks like this bug depends on the constellation in the real project, not directly in cobol-build:

• cobol-anagram-kata shows now problems. It uses a pristine template Makefile as supplied by cobol-build
• ToDoListe shows the bug, but it's Makefile adds an extra dependency from test and deploy to build. To there is the internal test: build depedency from cobol-build and an additional test: build dependency outside of cobol-build. Looks like make can't recall that the build target has already been build on multiple recursive calls to the same Makefile
