now voc adds dependency modules object files to the main module
compiling command line.
for example, if MM0 imports MM1 then if we call voc like:
voc -l MM1.Mod -s MM0.Mod -M
the commandline will look like
cc MM0.c MM1.o -static -o MM0 -fPIC -g -I /opt/voc-1.0/src/lib/system/gnuc/x86_64 -I /opt/voc-1.0/lib/voc/obj -lVishapOberon -L. -L/opt/voc-1.0/lib
