Makefile.inc: Stop running git repeatedly for each build
Currently, the coreboot makefiles repeatedly run git to try to set the KERNELVERSION variable and to fetch the submodules. This happens three times for every build. By exporting a variable, we can catch this on recursive makes and not run each of these steps again.
