Apart from the occassional `make bootstrap' or `git clean -fdx'.

In fact, INSTALL says that out-of-tree builds are ok:

  2b. Alternatively, create a separate directory, outside the source
      directory, where you want to build Emacs, and invoke 'configure'
      from there:

                 SOURCE-DIR/configure

      where SOURCE-DIR is the top-level Emacs source directory.
