Using line continuation (\\) in GNU Make \$(foreach ...) and
\$(call ...) resulted in the install section for many of the packages
not being defined. This resulted in 'skipping [package-name] no install
section' messages and no new package being generated.
We remove the line continuation from the parts foreach and call, in
ordeer to restore compilation and creation of packages.
