I simplified my explanation. I really used something like this:

for init/main.o:

init/.tmp_mc_main.s  : for the list file
init/.tmp_mc_main.o  : for the list compiled object.
init/.tmp_gl_main.o  : for the object converted static to global.
init/.tmp_mx_main.o  : for the merged list and global object.


The tmp.s was to keep the focus on the concept. But the actual 
implementation handles multi-threaded builds.

I use distcc and build with -j40. I had no issues.

Thanks,
