After a loser look at the sources and the build system I think it's better
(= much easier) to stay with shared libraries.

At runtime we do need both libguile and guile itself (it is used by
 lilypond-invoke-editor), and all of our guile must be invisible to the
rest of the system.

That means:
+ there must be no entry in PATH leading to our private guile, guile-config etc.
+ there must be no entry leading to libguile etc in the system library search 
path.

All that is possible without major changes to the sources... attached find a 
bash
script as a proof of concept. The requirements described above are met.
It passes the "full make" test without problems:
