Yann E. MORIN 9dac986696 core: add a make target to check the dependencies
Add a make target that will checks the dependencies of all packages.
This will currently only detect circular dependencies, but more tests
can be added later if need be.

This can then be used in the autobuilders to automatically report
dependency issues.

# - If a package has an unspecified optional dependency and that
# dependency is present when the package is built, it is used,

# manipulate the same file in the target directory.
