Just to clarify, this problem is not limited to the uname command.

Running "make" in /var/yp is failing becuase of a similar construct.
The Makefile does:

  test ! -d $(LOCALDOMAIN) && mkdir $(LOCALDOMAIN)

LOCALDOMAIN is `/bin/domainname` so this becomes:

  test ! -d `/bin/domainname` && mkdir `/bin/domainname`

but /bin/domainname has double output for some reason, resulting
in: 

set -x ; test ! -d `/bin/domainname` && mkdir `/bin/domainname` ; \
cd `/bin/domainname`  ; \
true || /usr/bin/make -f ../Makefile ypservers; \
/usr/bin/make -f ../Makefile all
++ /bin/domainname
+ test '!' -d pnylab pnylab
/bin/sh: line 1: test: pnylab: binary operator expected
