Makefile(s): do not enforce "all indents must be done with tab"

Our top-level Makefile follows our generic whitespace rule
established by the top-level .gitattributes file that does not
enforce indent-with-non-tab rule by default, but git-gui is set up
to enforce indent-with-non-tab by default.  With the upcoming change
to GNU make, we no longer can reject (and worse, "fix") a patch that
adds whitespace indented lines to the Makefile, so loosen the rule
there for git-gui/Makefile, too.
