Well, "make deb" is specifically tuned for debian/ubuntu builds.
The "make base" or "make programs" are generic and not tuned for
debian/ubuntu.

That's usually related to how the linker allows indirect references to
be linked in. Its behaviour is different in different versions. Usually
manually adding a -Llber (in this case) in one of the makefile flags
would fix this. But if "make deb" works, you already have working .deb
files one directory up from the libreswan/ directory.
