the lisp has to have some sort of extern linkage reference 
in order to choose the .o file from the archive. clearly there
is nothing in GCL that references those symbols as externs
so if you add libspad.a in the standard GCL linkage no .o
file will be selected from the archive.

but when the cfuns and sockio are included in the image
then the symbols they contain can be referenced by lisp
code which is written at run time.

axiom contains lisp code that uses the symbols externed by
cfuns and sockio.
