This should (currently) not be needed, for these two libraries are
(currently) considered to be part of libc.
(<http://www.gnu.org/software/hurd/open_issues/libmachuser_libhurduser_rpc_stubs.html>
and the thread starting at
<http://news.gmane.org/find-root.php?message_id=%3C20110329220143.GB5425%40const.famille.thibault.fr%3E>
have some discussion about this.)

Can you please post your toolchain's libc.so file (that is, the text file
of a few lines, not the binary libc.so.0.3).  Am I assuming correctly
that this is a i686-pc-gnu toolchain that I once provided you with?
