Thanks, Simon.  FTR I was able to solve it this way: 

$ PATH=$path:$PATH \
  LD_PRELOAD=$libcob \
  LD_LIBRARY_PATH=/usr/local/lib \
  make

where 

        path is cobc/.libs
and     
        libcob is libcob/.libs/libcob.so

These overrides are needed when cobc is called to generate its
documentation.  N.B. that override *always* needed to generate new
documentation from current source, because otherwise it will be
generated from the installed cobd & libcob, not the in-tree version.  
 
LD_LIBRARY_PATH is needed because of a mistake in the configure
script.  configure should set RPATH to include /usr/local/lib (or
wherever libcjson is installed).  As it stands, I get this:

        $ ldd libcob/.libs/libcob.so | grep not
                libcjson.so.1 => not found
