Static modules CSC link issue

Hi, Chickeneers! Eventually I found a small  issue in CSC .

The module 'mod' placed in file mod.scm and compiled by command

*csc -c -static -J -o mod-sfx.o -unit mod mod.scm *

can not be linked in main program by command

*csc -static mod-sfx.o -uses mod main.scm*

Usual name  mod.o like in manual, - is okay.

I think no one did this in such a way until one made cross compiled
versions in the same buildroot for different arch's using object file
suffixes.

Regards!
