I suppose it's a bootstrapping problem: to create (link) the shared
libmachuser / libhurduser, libc is needed.  And libc on the other hand
needs libmachuser / libhurduser.  Thus it's the easiest to build them
side-by-side.  Thomas / Roland, correct?  Of course, this isn't really
important anymore / isn't a problem anymore, as soon as there is a libc
(and the interfacing between lib*user and libc is set in stone).
