It should be possible to make FUNCTION.so available without using
COB_LIBRARY_PATH if you build the compiler yourself and don't mind
using a fixed directory.  

On most Linux systems, the shared object in loaded by ld.so, and the
default search path usually includes /usr/lib.  With the file in 

        /usr/lib/FUNCTION.so

I would expect it to work without COB_LIBRARY_PATH.  

If you don't like to put your Cobol functions in the system library
path, RPATH is your friend.  You might for instance use 

        /usr/local/gnu/cobol/func

To use that, RPATH is your friend.  When compiling the compiler, use 

        cobol_functions=/usr/local/gnu/cobol/func
        export LDFLAGS="-Wl,-rpath -Wl,$cobol_functions"

I'm happy to experiment with a working example.  :-)
