cl.el provides macros, which are expanded during compilation, and
which use cl.el internal variables. In the files which haven't been
recompiled those variables were still referenced to.

One could extract all common declarations into a file
tramp-declare.el, which is required by all other *.el files. In the
Makefile, all *.el files shall depend on this file. This would
recompile those files once the declarations have been changed.

But I'm in favor to introduce this mechanism for Tramp 2.1 only. Tramp
2.0 is the stable version which shouldn't see such reorganization, and
the case where it would be useful (Tramp 2.0.56) has happened already.

Best regards, Michael.
