You need to compile both modules at the same time. Do something like this for your two modules foo and bar:
modules/Makefile obj-y := foo/ bar/ modules/foo/ <= Your foo module modules/bar/ <= Your bar module
Then when building the modules stay in modules/ and execute: make -C <path-to-kernel-src> M=`pwd`
And to install modules: make -C <path-to-kernel-src> M=`pwd` modules_install
