This question is about Make, not GCC, so this isn't the best place to
ask, but yes, it can be done.

Makefiles can be used to do almost anything, especially building software.

The makefile rules simply need to refer to the .o files and they will
be linked to.  The most common structure of a simple makefile would
turn source files into object files, then link all the object files
together.  You simply want to skip the first step.
