misc: add top level makefile
Add a top level makefile to make common tasks easier. Supported targets: make - build modules make install - install modules (honors DESTDIR) make clean - clean up make tarballs - create source tarballs from current HEAD Note: "make tarballs" uses "git archive" so that it only works in a local copy of the git repository, not in a directory created by unpacking a tarball. Add *.tar to .gitignore to hide tarballs created by "make tarballs".
