Ouch. There was a recent commit related
to that exact issue which should have fixed this?
http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commit;h=11d6386

The Makefile.in in my local git repo is correct, i.e.
  man/uname.1:     src/uname
whereas in the dist tarball it's
  man/uname.1:     src/uname.c

I might get time to investigate some time tomorrow.

thanks,
Pádraig.
